I have had the worst experience with Comcast and have obtained the CEO' email.
If you are having problems with COMCAST
I have had several of the top people calling me back wanting to know how I obtained it and why i escalated to that level, simple they still haven't solved the problem!
So here it is and be sure to include my name in bold, TROY BOLLOM was the one that gave it you!
And if you don't have Comcast shoot him an email saying you would never get it from what TROY BOLLOM
