I used to work for Comcast in the Business Services division in Washington State. And yes, Comcast rips off it's business customers by charging some customers double the going rack rate for high speed internet.
The leadership of Comcast is not customer friendly, but forces the sales employees to sell the customer what the company wants, not what the customer needs.Buyer beware. I hate Comcast because After sale customer support is lacking, false and misleading sales practices, and poor employee morale.
I have sent this information to several broadcast stations and have written proof. Do not use their business services.
