Cancellation Nightmare

I have now had it with trying to get a contract cancelled. I keep getting transferred from 1 department to the next, from cancellations I get transferred to billing to tell them to update the system and back again and no one answers then I end up calling back and having to start over again. It's so damn frustrating because I have been trying since end of January to cancel this damn thing and it just cant get cancelled!!!! CAN SOMEONE PLEASE JUST CANCEL THIS DAMN THING FOR ME
