I signed up for ATT Uverse where I am due to bad CS with Comcast in the past (I actually get 2! whole choices out here). I paid for the in-home self-install, patiently waited the 3 days until my actiavtion date/time and hooked up my stuff.
Nothing.
I plugged it into the jack in the bedroom, still nothing. I switched phone lines, still no go. I hard reset the modem, and a couple of other things, still just that damn red light. So I call support, and after they run their checks conclude that a tech will need to be sent out. I ask them right there point blank if there would be a charge and I got a simple 'No' in return.
So, the tech comes out, unscrews the wall jack and it falls to the ground. My apartment had been renovated before I had moved in and I guess when they repainted the walls, they never reattached the phone lines. So, he screws in the wires, makes sure that it connects, and has me setup my att.net account. I signed nothing, and he went on his way.
Next bill there is a $110 charge on there that is simply labelled 'charge'. I call in and am informed that it was a $75 'Tech Completion Fee' and a $35 'Service fee'. They remove the $35 since it was charged in error as the $75 fee covered it. I ask them why I was charged, spend 2 hours on the phone with them, jumping from person to person and finally just tell them that I will pay the $29.99 for my internet service, even though for 3 days the first month it had gone out (I was out of town, it went out just before i left and was still out when i got home) due to an error on their part. But I would not pay the $75. They never put the charge in dispute, so the next month, my internet gets turned off due to lack of payment. I call them up again, wait on hold for 45 minutes out of an hour (when I wasn't on hold I was giving my ID info to a person and requesting a transfer) only to find out that their billing dept for my state had closed. So I call in the next morning, talk to a very nice lady and she reverses the charge after 15 minutes.
Having worked in CS in a call center, I can tell you that almost all of them are empowered to credit a customer up to a certain amount, apparently with ATT Uverse that is at least $75.
