Worst Cinema Experience

I've been to blue route mall on Saturday 20/06 to watch San Andreas, the 22h15 show. I needed to purchase 3D glasses and hot chocolate but the staff advised that they cannot assist me as the till is closed. I asked to speak to the Manager and he assisted to do the sale . During the sale the machine did not respond to my card, they tried 3-4 times and it did not go through. I had to then go to the ATM and draw money to pay for the items. After drawing the cash I rushed back as I did not want to miss the start of the movie and forgot my card in the ATM where the machine then swallowed my card. The total amount was R55.70, I gave R60.00 cash and they did not have change to give me as well as no slip. Due to this delay missed 20 mins of the movie. This morning I checked my bank statement and noticed that R55.70 went off my account twice. A total of R111.40 was deducted from my bank account and I paid in cash where I was told they cannot give me change. This is by far the worst cinema experience I have ever had in my life. Please put me in contact with the correct person as I have a refund due and would like to know how they are going to deal with this matter.
