My MONEY, Please!

made an online purchase on the month end of June, using a gift code that was given to me because of a initial failed online purchase. I have made countless requests to get my code back and my refund and this was a simultaneous transaction. Spoke to Tsholofelo Koele where my reference is ***/GO. I mistakenly deleted the code email but the purchase does show a voucher debit card purchase. I want my money BACK! I sent transaction reciepts and a bank statement proving everything. So why?
