Unsolicited debit orders are *******

This company continued to debit my account even though I was in good standing and credit with them. I have requested refund, via email and call center, and finally got an automated response over 50 hours later. They currently are in debit to me for R702, if I had an outstanding debit with them they would be harassing me daily on when will I be settling my debit with them. Unsolicited debit order are ******* and they have nothing to rectify this issue. The only contact I have had is when I phoned them.
