While disputing a $30 charge that I was not quoted the customer service rep said that the representative was probably afraid to quote that charge! Of course, no one at Comcast has any authority to waive charges.
While trouble shooting 2 additional digital boxes (which we are forced to pay for to have the same service we had before) the tech couldn't get the boxes to sinc up. He said he'd send a tech out. When I asked if there would be a charge, his respone "oh no." Guess what, I was charged and customer service refuses to credit the charge. Relunctantly they agreed to escalate the issue, however, it wasn't possible for anyone to call me back to let me know if the charge would be credited.
I'd just have to check my bill ??? In other words, they won't discuss that matter any further.
