Bad Service

I had a contract with nestar and was under the impression that its a 2 year contract. My 2year was coming up in October, so i sent them an email in September advising that I will not be renewing my contract. No one responded until November. They told me my contract was a 3 year contract. I asked for proof and was never sent to me. In November they debited and i reversed it, someone called me begin on Dec telling me about a due payment.

I explained to them the whole story. The consultant after a week of so came back saying they can close my account but there’s a settlement fee i need to pay. I agreed and a debit order was set. Money went off in January and i thought that was the end of it. Now every week i get calls from them saying i still owe more money. My question is that how can i owe when you guys decided on a settlement amount and i paid it in full.

No one can explain to me how that works, except that a consultant probably made a mistake.
