Refusing to Cancel Service

I called Comcast Business on April 27th to cancel my account and they said they were canceling it.

On May 30th I got a bill in the mail stating I need to pay for services from May 25th to June 24th. Even though I called to cancel the services. The ticket from my call on April 27th still shows as active so the other tickets they are "opening" are automatically closing out. During the call on May 30th they told me to call back in a week if the issue isn't resolved. 

That brings us to today June 5th when I contacted them again as the account STILL isn't closed. I absolutely WILL NOT be paying for a service I called to cancel on the 27th of April. I signed the cancellation contract and everything I returned the equipment and STILL they haven't closed the account and they "opened" another ticket and it auto-closed due to the original ticket still being opened. 

If they do not fix this and send the bill to collections and mess up my credit I will absolutely take them to court and report them to the BBB. I have written down all the ticket numbers they have given me over the phone. If this doesn't get fixed soon (even before it's taken to collections) I will report them and tell every single person I know and have my husband tell all his subscribers on youtube how terrible of a company you are. At this point these charges are fraudulent and I will not hesitate to take legal action because this is a case no lawyer will pass up especially since I did so well documenting every single conversation. 

Close out my business account and remove the fraudulent charges NOW.
