Frontier Communications Deceptive Trade Practice Texas

For the last three months I have been overcharged for my cable, and internet service.  I have called them every month to have the bill adjusted and they keep putting me on hold, and/or dropping the call.  The last three times I called, I was on hold with multiple people for over two hours.  before the call concludes, they agree to a price reduction, but when the bill comes, it's the wrong amount from the previous bill.  they agree to credit the bill the next month, but when that bill comes, it's the same as before, prompting another call where I have to go through the same mess again to have the following bill be wrong again.  Last month I requested a manager.  Again I was put on hold for almost two hours and the manager was supposed to fix the "problems".  But, lo and behold, I just received my February bill and it was the wrong amount again.

They are playing a game with the consumers, thinking we will just get tired and just pay the inflated amount.  It seems to be deceptive trade practice, and/or fraud.
