Double charge on single booking

On the 5th April at around 9pm I made a booking via the Ster Kinekor mobile website using my credit card. The booking was for 2 seats for a movie that was to be shown the following morning (6th April) at 11 am at a cost of R 113.50 . After making the booking I received 2 identical sms's from sterkinerkor stating the ref no. Movie name, time etc. A short while later I received a payment notification sms from my bank stating the transaction and my remaining balance . The next morning I see another payment notification sms from my bank stating a further R 113.50 had been deducted. After contacting my bank I was told that it's a billing error on the side of sterkinerkor.<br> <br> Assistance with the above will be greatly appreciated
