I deputed two debit orders, I got an sms that depit order has been disputed but my account balance was still R0.00 this was two days ago still there is no amount available on my account I also got sms that the depute went through from the companies now I have to pay double for the money I didn't even receive. Can you please advise as to what I need to do to have this resolved I am not available to go to any branch to have this resolved. I have sent emails to customer care same day this happen but had no response and had no ticket number.
