I work for Time Warner and have for almost 3 years, taken supervisor calls and dealt with this issue many times. When you have pixlating like that on your tv, its more then likely the signal coming into that box. Just because a tv that is cable ready with no box has no issues doesnt mean a tv with a box wouldnt pixilate. A tv that has any type of box requires a stronger signal to make it work properly. Usually if you are the only one in your immediate area that is having issues, its a single problem with the lines to your home, which this is what is sounds like.
I completely understand being upset with it but calling in and demanding a supervisor, thinking that a supervisor in CUSTOMER SERVICE is going to be able to tell you exactly what is wrong and what needs to be done to fix it not going to happen. When you talk to a supervisor, just let them know your frustrated which Im sure they can tell by talking to you and they will get the information to a Tech Super (which will be the one to fix the issues) so he can get it fixed for you.
As far as Time Warner fixing the Former Adelphia areas, this is a constant work in progress. You have to understand that some of Adelphia's plants were and are a little behind the times and its going to take Time Warner time to update all of these. People complain that they cant get certain services there like Phone, RoadRunner and HD....what is the point in trying to give people in these areas those services if we cant run then properly to begin with!?!?
Not saying that you dont have a reason to complain, bc I definately would, but I can tell you from taking the supervisor calls, that the supers you talk to are limited to what they can do bc they are in a CALL CENTER. More then likely in a call center in Zanesville and Lima, so its not like those people can just run to a Tech Super for your area and be like hey this customer is having issues, can you fix this? We rely on emails for alot of communication so that in itself takes time!
No matter what company is it, there is always going to be good and bad that you hear about them...WOW, Insight, ATT, Verizon, and Time Warner. I get my share of people that complain all day about any of these companies and I get my share of people that complain about Time Warner. If any of these companies were perfect, none of them would have retention depts, trouble calls to fix issues, etc.
