sent phone back 15 days ago, Xfinity still has not closed account

Chatted with 6 agents, spents 10 hrs of my life dealing with this  horrible, [Edited: "Inflammatory"] company. Now they say it takes 3-4 weeks for Fed Ex to inspect the phone.  I  called a lawyer; he stated this is a civil matter and said it would be best to cancel the credit card which the website of mobile will not allow you to delete.  I believe this is illegal to force someone to store a card after cancelling a monthly subscription, which is what phone service is.  I did receive a credit for the first two payments, but I will not do this chatting anymore.  I sent the phone back, didn't even take it out of the box.  Cancel the account. Period.  No other discussion needed.

I cannot get anyone to close the account even when i have sent the phone back.  I have informed FTC, FCC, and the attorney.  Xfinity expects us to just sit [Edited: "Inflammatory"] .  The system can no longer take my money.  If my credit gets ruined, believe me when I say I will take this to arbritration.  I don't live that Far from D.C. and if necessary, I will drive to Philadelphia.  I haven't done anything wrong, [Edited: "Inflammatory"]

I am not private messaging anyone, nor any such additional wastes of my time.
