Continued Horrible Experience with Xfinity

So we upgraded our plan to include a sports package. We were told the new channels would be active in 15-30 minutes. When the new channels were not active after an hour, we called Xfinity and spent 20 minutes just trying to reach someone. When we finally connected with someone on the phone, we were told that the change could take up to 24 hours to take effect. So we waited until the next day and when we still did not have the new channels, we had to call Xfinity once more. We spent 30 minutes on the phone only to be told that the reason our new channels had not taken effect was because the work order was not complete by the person who initially assisted with the upgrade. We were transferred to someone who could supposedly complete the work order. After another 20 minutes, we were told that the Xfinity system was displaying error messages all around and the work order could not be completed for 2-3 hours. They said they would have given me a credit for all my troubles but could not do so because of the system error. The agent said he would give me a direct line to call back and then proceeded to give me the 1-800-XFINITY number. All the while, my bill increased immediately so that part of their system was apparently not experiencing any "errors." So right now we still do not have the new channels, we have an increased bill for services we do not receive, and another horrible experience with one of the worst companies out there to add to our growing list of horrible Xfinity experiences. And to make matters worse, my bill increase to an amount more than the amount I was told it would be. Of course it did - Xfinity always does that. I will now have to spend even more time addressing that issue.
