Unhappy Comcast Customer

I have been a Comcast customer for probably 18 years. 13 through my condo which I had no dealings with, but 5 since I purchased my home. For the most part things were fine, despite the fact periodically they raised the prices or required new equipment without letting me know.  I contacted Comcast to see about having my bill reduced and possibly add DVR service. Increases are automatic, decreases you have to ‘beg’ for. Comcast has chosen to not respond to me this time. No phone calls no e-mails. I so want to send this to the newspapers. It is wrong.
