Incorrect debit order

This is really upsetting!!<br> Month ending december, I was debited R623.00 instead of R425. It's a month later and after logging a call with them ( Call ***-i45) and still no communication when this error will be corrected only escalation after escalation after escalation. I don't know how many times I must tell DPP I do not have an explora it was never delivered so to tell me it was an outstanding amount for DPP is incorrect. Can this be resolved as I am seriously considering cancelling the debit order on my account as it is not the first time this error has been made.
