Boycott COMCAST - Internet, cable, phone

I recieved an ad from Comcast today. It had Spanish in large print and first, while English was in small print underneath.  I tried to get phone numbers to management, but to no avail.  I was told it is the Post Offices' fault. I told them  they paid for the ad not the Post Office.

How do I get these numbers? PLease Boycott these UnAmerican creeps!
