cancelling of contract

It is now 2 months and still my contract has not been cancelled. I was advised to mail settlement letter mailed to my by Autopage , which I did and was advised that the amount reflecting is not the correct amount due to columns missing from the e-mail received from Autopage directly. The amount reflecting is the amount that was given to me telephonically on the same day. I have proof of the amount and was only given an apology for the inconvenience. I cannot understand how nobody can assist after asking for the matter to be escalated and I have not yet received a response.
