Still waiting for my Refund

Our bond account was incorrectly debited and paid to someone else's account.They acknowledged it was their mistake an would rectify it. One week and 15 calls later still no refund. No one in management available to help. Always in meetings.Consultants so rude. No one ever calls you back. Pathetic service. My Bond payment goes off tomorrow and now my account will be in default because Nedbank made an Error and still no refund.<br>
