Line suspension reported, but still being billed

I left my home at Unit 66, Monterama, La Montagne at the end of January. Reported the move to Telkom in Feb, asking to suspend line until further notice. Charged in March, went to center in Menlyn again, asking what is happening, they said the debit order is still running, but will cancel with money paid back. April same story, but debit order STILL running from Telkom side. They said I would be refunded, not to worry. In May, AGAIN the same story. So to date, I've paid for four months worth of internet and telephone lines that I HAVE NOT EVEN USED!!!!!! I have also received no refund to date. I will await the deduction in June, then take the matter to court. I believe I have now been patient enough.
