After 9 years and managing 3 lines, I am completely done with this company. After I dropped their home internet, they penalized my account with hidden fees. Then, a customer service representative lied to push a plan change, explicitly promising me a "6G" network upgrade—which is flat-out deception since 6G technology doesn't even exist yet.Following this fake upgrade, my service cratered to a terrible 3-bar connection, and our third mobile line completely broke with a "No SIM Card" error. This phone belongs to my son and connects directly to his Dexcom monitor to track his blood sugar. Because Xfinity killed his cellular service, his medical readings completely blacked out while he was at school, forcing me to leave work for a medical emergency.I spent 3 calls totaling 6 hours over 3 months trying to get this fixed. All they offered for leaving a child without his medical tracking device was an insulting $10 credit. Loyalty means nothing to them. Save your family the nightmare, avoid their bundle traps, and go to a carrier that won't compromise your safety or lie to your face. Stay far away.

The call reps aren't even in america, ive been a customer for 8 years and they canceled my payment plan on my smart watch and is trying to charge me 304.31 they said it was canceled in April yet im being charged in September? I told them I did not cancel and they told me yes you did, so ive been fighting this. So I am going to be switching to a different carrier as I will not get scammed, do not use xfinity for any of its services they will rip you off big time.

Xfinity has made offers that they don't deliver on or change before the end of term. This is the worst large company I've ever experienced.

Everything is fine as long as it works. However, when you actually need to speak with a customer service representative, it takes far too long and resolves absolutely nothing. I received an email from Xfinity… "Your Xfinity Mobile promotion will expire on… Here are the details: Expiring promotion: promo bill credit This promotion will be removed from the following mobile line:…" When I contacted them about it, they told me it was spam. I eventually requested to speak with a supervisor, but that didn't happen either—I was just told someone would call me back. I only hope the changes announced in that email don't actually take effect. If they do, I will be filing a complaint with the BBB, and they will definitely hear from me. Relying so heavily on AI for customer support has made their service completely inefficient and impersonal.

Between 3 of us, we spent 6 hours on the phone (with 6 different Xfinity reps) to try to add another cell phone line to our existing service, and they still failed to do it. They employ untrained people at call centers who are not proficient at doing what needs to be done. Xfinity clearly just wants maximum profits regardless of hours and money wasted by customers.

Two years as a paying Xfinity customer: frequent outages, internet speeds that rarely held up, and constant buffering when streaming. I paid every bill anyway. The real problem started when I tried to leave. Cancelling requires a scheduled callback booked days in advance. Miss it because of work, and calling back dumps you into an automated portal with no path to actually cancel. I tried multiple times, including through their online portal, and finally sent a written cancellation by email in December 2025. They billed me for another month anyway. Then they sent the balance to a collection agency. I disputed it in writing within the deadline, and legally they're supposed to validate the debt before collecting. They never did. Instead, the debt quietly moved to a second collection agency, and I had to start the whole dispute over again. So the full experience: mediocre service, a cancellation process designed to keep billing you, and a collections pipeline that ignores written disputes. I've now filed FCC and CFPB complaints just to resolve a $208.98 charge for service I asked to cancel. If you sign up, document everything from day one, especially any attempt to cancel. You'll need it.

I just had the sketchiest conversation with Xfinity mobile customer service. I wanted to see about saving on my mobile service by switching to Xfinity, but the entire time I was trying to ask questions about keeping my phone and phone number, fees, monthly bills, and data plans, the rep kept bugging me for sensitive information that I know is used to set up service, essentially trying to force me into a sale I was not informed on. When I asked to speak with someone else I was put on the phone with someone who sounded suspiciously similar only louder, I worked for a very long time on the phone, I know when someone is putting on an impression. They too kept pressing me for personal information to authorize the sale, they also assured me that there would be no charge a suspicious amount of times. When I finally decided to go with my instincts and back out, I asked if I could get the same thing done in store, which I already knew the answer to was yes, but she tried to keep me on the line saying they'd charge me more at the store. Overall very sketchy vibe, I can imagine people get signed up for all sorts of things they didn't ask for this way.

This should allow for a zero stars option. Anyway, I don't cry often but I have to tell you, I broke down sobbing yesterday due to the ineptitude of Xfinity Mobile. I've been with T-Mobile for ten years. No issues at all and no problem contacting a real person. I decided to switch to Xfinity because we have their Internet and would get a big discount and as we are on a fixed income, I thought, why not switch? When I tell you that from jump street, the process was beyond effed, I'm not kidding. Everyone I spoke with (except the SALESPERSON, of course) was in another country, which would have been fine if I could hear/understand them. Long story short, they screwed up the porting process on our two lines and after hours of back and forth, I called T-Mobile and told them I wanted to reactivate. They couldn't have been kinder. Perhaps because I was sobbing! Anyway, they walked me through what I'd have to do, which was to get a transfer pin and account number from Xfinity. THEY WOULD NOT GIVE THIS TO ME OVER THE PHONE. They kept telling me to go to the app but I tried to explain that the app didn't even reflect our order of mobile. It's like I made the order and it vanished into the ether. I finally went into an Xfinity store and got the info I needed to get the hell out of Dodge. I then called T-Mobile and got service ABOVE AND BEYOND what one would expect. The gal I was dealing with went so far as to call me back in the evening to make sure the deactivation process was going as planned. AND I COULD UNDERSTAND EVERYONE. No long waits on the phone, nothing. Xfinity wants your business and that's it. They get their money and you get grief. Do not, under any circumstances, get Xfinity Mobile.
