2 months Refund

I am a customer who is very frustrated by rain .. I have been paying for arreas every month with no line on. I have asked them to cancel this beacause when I joined I was told it was not a contract and if no payment made for that month no line will be opened.. I spoke to the consultant when I joined and i am 100% sure they have these call records. I paid last month and i was told i am in arrears. This morning again a debit order took R621. Even when I have cancelled .. I tried to cancel on my side but manange option does not allow me for cancellation .. I went back to them and told them u am having issues of cancelling on my side ..they gave me ticket #***8 every time.. which company debit your account every single day? All of these bank charges I have to pay every single time they visit the bank?.. all i want is my 2 months money back and cancellation letter from their side. I want 2months refund back.
