Credit Card trans. not reversed and no service

I went to Ster Kinekor the Grove to watch a movie on 27 Dec. We bought some popcorn, coke, etc. and I tried to pay with credit card. <br> <br> The first time the card was swiped an amount of R270.80 was processed and I received confirmation by sms that it went through. The lady behind the counter said the transaction did not go through and asked that I swipe again. <br> <br> The second time an amount of R255.80 was processed on the same card and again I received confirmation from the bank. Again the lady said the transaction did not go through. I then paid with cash. <br> <br> The lady said the credit card transactions would be reversed as it did not go through on her side but this has not happened. Neither of these transactions have been reversed. I also do not know why she first charged R270.80 and then R255.80 because we did not change our order in between swipes.<br> <br> I called the Grove numerous times and no one picks up the phones. I then emailed the Grove branch on the 4th of January. I still have no response. <br> <br> I have not been to the physical branch because it is out of my way and I should not have to. <br> <br> At this stage I am out of pocket R526.60 and cannot get through to anyone to assist
