Telnyx never fails to deliver. Their customer service is the best and I always recommend Telnyx to my clients.

A telephone call on my mobile this morning from a number I checked on Who called me? Website is shown as being owned by this Company. The caller asked for my husband and then proceeded to ask about his debts. My husband died in 2008. It was very upsetting, This Company clearly allows scammers to use their services with impunity. Disgraceful. Addendum: I have subsequently heard directly from the Company who advise that they have passed the information I supplied to their fraud team. Given the nature of their business it is clear their system has been abused by a client. If the caller had targeted me I would have just hung up and blocked but using the name of my dear husband - 15 years this year and only 60 when he passed,after 44 years together was totally unacceptable.

Hi Nanjay, My name is Mark Morse with the Customer Success team at Telnyx. Thank you for reaching out to report this occurrence. I would recommend utilizing our abuse reporting that connects directly to our fraud team so we can dive into the call example and stop this behavior indefinitely on the platform. https://telnyx.com/report-abuse Telnyx is a self-service platform where users can sign up, create an account and start sending/receiving calls. This behavior described in your review was conducted by one of our users and we are here to help pinpoint that user and ensure you are not called by them again and stop this behavior once and for all. I would like to work with you directly on this matter and stop it, but Trustpilot, unfortunately, does not give me access to your contact information. If you could email me at [email protected] I would like to start the conversation to get this resolved. Looking forward to getting this resolved with you.

Telnyx has been amazing for the small business person like me! Absolutely no issues at all. Slightly disappointed and confused about specific number requesting though, will go through another carrier to purchase toll free numbers and then port them in as Telnyx’s NumberOps team tells me and redirects me to use the portal to search for the available numbers only section. I thought I opened a ticket through a button to request a number that Telnyx did not have available?

Hi Erik, Thank you for reaching out and for your honest feedback. Regarding your specific feedback on number availability, I will ensure to share this feedback with our numbering team as this is not a typical experience when using this feature. For now, I would suggest reaching out to [email protected] when you search for a toll-free number that is not readily available for purchase. This will ensure our support team can work with our numbering team internally to see if it is possible to obtain your requested numbers. If you ever have any specific questions or concerns, feel free to reach out to me directly via email at [email protected] and I would be happy to assist as well. We look forward to continuing our partnership in 2023!

Non stop harassment from this spamming company. I thought harassment was against the law???? 7 calls to my business number in one day using different numbers. I have asked so many times to be taken off the dater base but to no avail. Why the U.K. government allows such a company to exist is beyond me.

Stop spam calling me, within the last few hours I've had 7 spam calls. I don't want your services, I never asked for your services and you can delete my records from your system. If you call me again I will be sending you an invoice for my time spent listening to your pathetic attempts to scam me. It's 2022, get a life you sad sad company. And as for David Casem you are a disgrace of a business owner for allowing this to happen.

I was contacted multiple times by an abusive timeshare telemarketing agent. Despite not requesting their service or their product, I told the agent not to call again. The agent threatened to call me "all morning, every morning". The agent then continued to call, using different source IP phone numbers. I have now blocked all of the numbers that were used. Telnyx should do a better job a screening their customers, and/or implement some simple software fixes to prevent this form of abuse.

I made a recharge (the first and only one), and bought a number. Minutes later my account was suspended for "violating" their terms and conditions and "ABUSING" their "one time password system". When it is totally false. I only received 2-3 SMS, that's not "abuse" for all!!. Now they want to keep my money. EDIT: They only returned $1.87. They kept the rest. It's literally like download a game and being banned out before playing it, and not wanting to give you your money back. Be careful!!!

Hi Alejando, My name is Mark Morse on the Customer Success team here at Telnyx. To provide more context regarding your account getting blocked, it was blocked for direct violation of our AUP for using inbound messaging for OTP. This is not a use case we allow on our platform due to the high volume of fraud that occurs in the industry with this type of use case. Regarding your refund request, immediately after suspending your account, we issued a $1.87 credit back to your payment method on file to ensure the money you put on your Telnyx account was given back to you. Feel free to reach out to me directly ([email protected]) if you have any further questions or concerns regarding your refund.
