Zero responses, Still being charged for DSL service which I cancelled last year

<p>I Cancelled my DSL subscription service in September 2015. I'm STILL being charged for it to date despite calling in to try get a hold of someone who could help me. </p> <p>I've now also been bounced between various billing departments who can't or won't help me and have been given dead numbers to call regading billing disuptes. Emails go unanswered. </p> <p>When I refused to pay the cancelled DSL service my entire line was suspended and then I was charged fully for a suspended line. </p>
