Issues cancelling account

I am experiencing the same issue with cancellation for my business. I called last Thursday spoke to an agent, said needed to close my account and line  got “disconnected”  THREE TIMES! Three different people! Finally the 4th stayed o the phone, reluctantly, I was [Edited: Language] and I let them know. After unsuccessfully  trying to persuade me to keep the number (for a store I’m closing) and transferring it a cell phone ??? [Edited: Language] He said I would receive an email after the call, with a document  to finalize the cancelation. Never received the email. 

Looks like all the agents work on commission and if they don’t sign you up for something they don’t get paid so they don’t bother?

I am livid. I have 3 other businesses with comcast. Despite the headache and the $500 it’s going to cost me, I am going to port my phone numbers and stop paying. I guess the only way is to get the service shut off and wait for a final bill?  I am keeping track of all of my failed communications in the  hopes that someone with any business sense [Edited: "Inflammatory"] will help me.
