NEDBANK - IS SOMEONE COMMITTING ***** ON MY ACCOUNT AND WHO CAN FIX IT

A transaction debited to my revolving credit and also to a budget facility is impossible to fix. After over three hours on the phone and being transferred from person to person I was promised a call back yesterday. Never happened. They deducted the amount from my revolving facility but also opened a budget account. They have subsequently transferred the balance to my revolving but not the amount they took off as the "monthly installment". Of more concern is that the staff argue a minus is in fact a credit and a deposit is in fact a debit. And the statement that "the transactions we see on our side is not the same as you see on your side" WHAT????????? Are they running two sets of accounts??? I sent screenshots and you can clearly see I am being charged TWICE for the same transaction (the running balance confirms this). I just don't have the energy to sit on the phone for another three hours to be transferred from one *********** person to another.
