Unimpressive customer service
It took five months before my email was answered which took at least two more emails. When I was finally offered a replacement at a discount as the warranty had finally ran its course, it was then cancelled because there were none in stock. Not impressed with the customer service. I had issues for at least 6 months and after checking everything else, it took a while to figure out that it was the product that was causing the issue then my original email was not answered.

Hello Bonnie ... Thank you for taking the time to share your experience. We apologize for the delay in responding to your original enquiry and understand how frustrating that must have been, especially while you were trying to determine the cause of the issue.
After reviewing your case, it appears the call blocker was originally purchased in 2023 and the reported problem involved your mother's number being blocked. In many cases, this can be resolved by unblocking the number directly on the unit using the following dial-tone code, which is also included in the user guide:
**6# (wait for beep) [enter number to unblock]# (wait for beep)
As the device was outside its warranty period, we offered a discounted upgrade to a newer model. Unfortunately, there were difficulties processing shipment to Canada from our US warehouse. While shipping to Canada is possible, it can sometimes be costly and take considerably longer than domestic deliveries.
We appreciate that this situation did not meet your expectations. If you would still like to discuss a replacement device, please contact our support team again and we will do our best to explore the available options. Alternatively, we recommend trying the unblock procedure above if you have not already done so.
Thank you for your feedback, as it helps us improve both our support and communication processes.

The device has not blocked any marketing calls. Appears a total waste of $!!

Our Call Blocker is designed to actively reduce nuisance and marketing calls for thousands of users, with performance improving based on how it is used.
For best results, Caller ID should be enabled so the device can accurately identify incoming calls. Using the red “BLOCK NOW” button helps the system quickly learn and strengthen future blocking. Additional control is available through programmable codes, including the option to block entire area codes for more targeted protection.
With the right configuration, the device becomes increasingly effective at stopping unwanted calls. Give us a call or email and we can help you get the best out of it.

Easy to install and had stopped most calls
Easy to install and use. Blocked a large number of calls right at the start. Getting 25-30 calls before installing, reduced to 5 to 8. However, once family wasn't around to instantly block calls getting through, the calls increased up again. Certainly not to the 25/ day but 5-6 around both lunch and dinner times. We're continuing to reinforce not answering every call unless a known name appears. But overall, a good product that has drastically diminished calls.

Thank you for your review! We’re so pleased to hear the Call Blocker made an immediate difference and helped cut those daily calls right down.
You’re absolutely right, unanswered nuisance callers often get the message eventually (they can be persistent little creatures!). Glad it’s bringing more peace and quiet overall, and thank you for sharing your experience.

Tamed the scammers and spammers! No more unwanted calls!
Both my mother and mother-in-law were getting in excess of 50 scam/spam calls a day. I purchased the V10000 model and programmed in allowed numbers on the white list. The resulting peace and quiet is heavenly! The company was expeditious in returning answers to my emails as well. Very pleased! Thank you CPR!!
