I called May 1st to cancel my service completely.  I returned my equipment May 1st.  On May 3rd I did a chat with an agent who told me it was cancelled.  two weeks later I get a bill for the month of May and the Month of June.  I call again and they said no one cancelled my account but he will gladly do it now.  It's now a week later and my account is still open and now they are telling me they are unable to remove the charges for May.  This is ridiculous.  

Is the date on the billing statement before May 1st?  If so, it was generated before you cancelled your service.
