Refund

On Wednesday 19 Nov I went to Clicks to get something for what I could feel is a cold on its way. The amount was R247.13, I tapped my card and the machine showed NOT AUTHORISED. Tried 3 times again with same results. Went to the ATM and withdrew some cash to pay. Made my payment, got my products on off I went. The next moment the sms’s starts going off like crazy. The amount of R247.13 was deducted 4 times from my account. Last 2 did not go through due to insufficient funds. The first 2 did go off from my account. BUT I paid cash, so Clicks needs to refund me R494.26. After numerous emails / phone calls / trips to the store no one can help me. The Complaints Resolution Team said it can take 2-3 days to resolve the issue. No reply, update ANYTHING from their side. My bank needs a letter from them stating that the 2 amounts were authorised but needs to be reversed. But no one is attending to this seeing as there is no communication from them.

Please help!
