Billed after canceling my contract! You suck!

I cancelled my contract in September only to be billed again for 1 October. I called the center where the person from cancelations put me on hold for 20 minutes, but apparently they left. So this guy put me on hold and left, great service! I got through to a customer care agent who was helpful, she told me the contract was only suspended and not cancelled. I want the money billed removed and this contract cancelled!!!!!!!!! I did my part by calling and canceling. I will not pay more for this bull**** contract!!!
