MY MONEY BACK PLEASE!

I paid for my meal through the drive through with my credit card and the cashier said there was a problem with the machine and it didn't go through, then I switched to my debit card on another machine and she told me that machine was having the same "communication" issue so I paid cash. I asked for transaction cancellation slips for the card payments and she said the machines don't issue them. I paid cash and on the 10th Oct the R73.90 went through my transaction 470724*978406 It's a pending transaction on my credit card dated 6th Nov for the same amount transaction VODSDL1QTYXG but shows up twice other transaction code is VODS2XFVTYXG I want the pending transactions cancelled and my money back for the duplicate charges. Your system should show that one purchase on the 6th Nov was charged 3 times!
