Bad service Multichoice

I am a commercial subscriber with Multichoice. yesterday all my decoders were suspended. I called their call centre, the lady ensured me my account was up to date, no reason could be given why service is suspended. the lady said if I pay R3200, my service can be reinstated. I called about 5 times the credit controller, 3 different ones, none answers their phones. I paid the money in and wanted to see a statement of my payments, but none could be given, I wanted to see why Multichoice said my account is in arrears. Any reasonable company should be able to provide the customer with a statement of payment and to disclose why they suspend your service.
