Still being billed after closing account

It seems that Autopage are still deducting money every month even though I cancelled my contract with them. in September 2015. It is impossible to contact them telephonically - their automated phone system promises to put you through to an actual person after you press a lot of buttons but nothing happens.<br> <br> Well, something happens: they take money from me every month!<br> <br> All I want is some communication with them and for them to stop taking my money!
