Frustrated by Pathetic Service MBD Attorneys and Standard bank

My cheque account and overdraft has been handed in to MBD by Standard Bank without my knowledge while I was making regular payments. SARS has now made my refund into this account and the amount exceeds the amount owing to Standard Bank. It is very difficult to reach MBD consultants with multiple transfers from switchboard and waiting queues. When I finally reach the end of the queue a recorded voices asks that I leave my numbers to be called back. I try again and when I do reach a consultant they have now way of assisting me and refer me back to Standard Bank and are reluctant to escalate the matter to their seniors. This is such a frustrating process.
