Refund for unauthorised debit

Loan ***<br> Took out a loan to cover a shortfall. 4 days later repaid the full loan amount. Then on the 09 Feb 2015, provided proof of payment. During February 2015, my account was debited for the same loan account. Contacted Get Bucks (Stephanie) on the 26th February 2015 and had a discussion told to provide proof of payment and money would be reversed. Since then have made numerous calls and provided proof of payment but to date, have not receieved refund or even a cuortesy call. This is costing money and is ridiculous. If dont get refunded soon, I will be raising the matter with the National Credit Regulator as well as the Consumer Commission as this is unacceptable and unfair.
