R5000 incorrect debit not paid back.

On the 15th of March, Telkom Mobile erroneously debited R 5,475.00 from our account. Two weeks later Sibusiso sent an e-mail acknowledging that this was in error, and credited the amount to our Telkom account.<br> <br> However, he also promised that the money would be refunded into our bank account, but this has not happened. We sent three follow-up e-mails, inquiring when the money would be given back to us, but he hasn't responded.<br> <br> This is a large sum of money that has been effectively ****** from us for over a month now. Telkom, please please please can we have our money back? :(
