Double deduction of funds

Dear Sir / Madam,<br> <br> I have made a purchase at Pick 'n Pay Woodmead on Saturday 29-08-2015 with my discovery credit card. The Transaction did not complete on the till but the money was deducted from my card. The teller could not finalize the transaction and retried my Discovery card again and it declined due to no funds (funds was take on first attempt.) I was forced to swipe my FNB Cheque card to complete my transaction so I could take my groceries. I was waiting for the funds to be returned to my discovery card due to it not completing in the first place but it was never refunded. I was then told by Pick n Pay Woodmead that it would take 3 business days... in the meantime I am R3389.17 out of pocket. <br> <br> Coen at the Woodmead branch tried to help but returned today saying that discovery should release the funds to me, but discovery says that the amount was approved. Iam being sent from pillar to post and can not get my money back. <br> <br> I NEED PROPER ASSISTANCE ASAP!!!
