Xfinity Support

I called in on around Jan 30 to cancel my Xfinity account.

My account is still not cancelled and I am receiving the payment over due bill emails.

After that I called 2 more times and also chat with agent.

Eveyone is saying standard answer "Nothing to worry", eveything will be settle down when your account is closed.

I don't understand why my account is not yet closed, this is annoying and painful.

Last time agent told me that it's pending cancellation and I don't get what that means.

Can some one help me to resolve this?
