failed to cancel contract

In April 20 I went into the branch to cancel my expired contract. This was recorded in a book and would have been processed the following day. The phone and number has not been used since then. To my surprise I noticed that the subscription has never been cancelled. In fact I have been receiving numerous calls regarding upgrades and I insist that it's supposed to be cancelled. We went into the branch a week ago to try and get to the bottom of this and we were told that the manager would contact us the following day once again. I saw them Lodge our complaint. It's a week later and we still have not heard from the manager. Once again we are faced with appalling service from Autopage.
