Gateway Issue

I have been having issues with lost signal, pixilation and picture freezing. I am able to restore service after rebooting the gateway. I contacted tech support, Kevin, explaining the problem. He told me that I need to reboot again. After rebooting he decided to run some internal test. He told me that there is no problem showing with his test. 

I asked him if he could send a replacement gateway and was curtly told "no way". If I want/need a new gateway a tech needs to come out for the low cost of either $99.00 or $149.00. I have never paid to replace defective equipment in the past and I am not about to pay now. Kevin has given me a reason to seriously consider switching to another provider. I have been a ATT home phone customer since 1973, wireless since 1991 and UV since 2010.

I was told several times during my conversation with Kevin that I was a valuable customer. If this is the way that ATT treats valuable customers I hate to see the way ATT treats a non-valuable customer.
