Cancel service

I have had two call back where the operator has said they would send an email confirming my cancellation I have not revived any emails nor anything saying my service has been canceled. You lot are scammers and I will be telling everyone I can to never use xfinity or any comcast product. I don't even think I spoke to a real person I am quite sure it was an AI that claimed to be real. The mere fact canceling isn't a few buttons but I have to get a call back is annoying and should be illegal.
