***** deductions

For a long time now i'm having a debit order of R30 deducted of my cheque account by a company called \Club MCC"with the heading \""Rental - Lease\"" with a reference number. I was able to put a stop order on the transaction and the Presige banking consultant were very helpful. Everytime I get in touch with Prestige they suggest that they can reverse but it's up to me to cancel the debit order. However if I do not know for what / who the debit order is, how am I able to trace the source to stop it. Very uneasy about the prospect of my account being hacked with no avenue to resolve it.
