still trying to cancel

After my last post, I received a call from Directv. I was told that they could not access my account because it had been closed. I informed the person that on March 27 I was billed $111.25 and my account shows that I will be billed again on April 29. The bill lists an account number, my name, and my address. The person told me she would check and put me on hold. After 22 minutes and a few seconds, I was disconnected. I have now spent 95 minutes on the phone with Directv to try to cancel my service, to no avail.
