Xfinity Runaround

Here's the situation… I was on a chat at 2:30 on a Thursday afternoon about something totally different and it was offered the opportunity to quote lower my bill". I said sure, explore the options, but I do not want to have any loss of service or entertainment options. The representative assured me that would be not a problem and offered me a $70 reduction in my monthly bill. She then deactivated to cable boxes on my service which resulted in six more customer service calls to figure out what was done wrong, which resulted in the reactivation but deletion of multiple channels that when I finally got somebody on said we will add them back on but now it's gonna be $70 more per month. What a joke!

Who handles this at a senior level that has an ounce of common sense?
