Trouble Cancelling My Service and No Response

I am struggling to cancel my subscription (Fixed Line Unlimited Lite) due to no infrastructure at my new home to accommodate me.I sent in my cancellation request and I keep being billed for a service I can't use. I reached out to the accounts department and went to the Table View branch numerous times, where they just pull up their shoulders and say they don't deal with it. I refuse to pay the added bill, and I agree to settle my outstanding arrears prior to the new invoice. I can't pay for a service that I cannot use!
