Their paper bills do not make sense. Their paper bills amount due never matches the Xfinity.com amount due. They tell you whatever they want, and half the time it's not even true. I have even been lied to by a manager. He assured me that money that was taken out of my account without my authorization would definitely be put back within 5 days. I called everyday, the fifth day I was advised they don't know why he promised that because they just will not put money back. They said call your bank and tell them you did not authorize the transaction, that's the only way to get the money back. I asked what about the NSF you caused, their reply, that's your problem. Here's the kicker…. When the bank reversed their transaction, Xfinity CHARGED me $30, on top of the $30 NSF fee I incurred! Yes they will give you credits, but they will find other ways to charge you. Worst customer service ever! I hate to even call them because I know they will just read their script, give you "misinformation", and never do the right thing.
