Capitec not offering the service they promise

When we paid our debt last month we made a mistake by paying R4000 into the wrong account. We phoned Capitec immediately and reported this they gave us a reference number and said it would take 14 working days for the money to reflect back into the account we phoned again after the 14 days and they were giving us the run around we only get paid month end and we need the money back in the account.
