Pathetic customer service

8th of feb i booked 2 tickets to watch 50 shades of freed for the opening on the 9th of feb. However, i booked the incorrect time after the transaction was completed. I asked the manager on duty to kindly exchange it for the earlier show which was 8pm. He said it could be done and was gone for about 5 mins. I specifically told him it was for tomorrow (9 feb) and he confirmed if the seats was still okay. I went home to return the next day to watch the movie that i had booked for. My fiance and i was seated at k1&2. Another couple then came in and claimed they were k1 & 2 and we all assumed they doubled booked us. Bare in mind, these tickets are checked before entering the cinema. Without arguing we stayed seated and they sat behind us. The movie eventually started and about 30mins into the movie, 4 people comes in and claims the couple behind us are seated in the seats. They were making so much noise that we could hardly hear what was going on. The manager was called and another employee then checked our tickets to ensure it is the right ones. He then double checked and came across our tickets being booked for the 15th of feb. Right there and then we were put out of the cinema. Can you imagine the embarrassment because we specifically booked for the 9th of Feb and now we are being told, sorry, but your tickets isn't for this show. THIS WASN'T OUR FAULT. BLAME THE IDIOT MANAGER WHOM EXCHANGED THE TICKETS. He wasn't there and another lady assisted us but by this time i was so furious cause halfway through the movie we got put out for something that wasn't our fault. We didn't check cause we booked for the correct date. So my question is, why didn't the lady who checked our tickets notice it wasnt the correct date? Anyway, im still ****ed off because i never got compensated for the tickets i bought. The manager on duty called her manager to authorize that we get a refund and said she would call us back (10th feb). I received no call and went back to hear the manager had "issues of her own" and couldn't sort it out but will call back monday the 12th feb. I was cool with that but monday passed, so did Tuesday and guess what? Its ****ing Wednesday and no one ****ing called me! Your empty promises still hasn't given my money back nor compensated me for my eats i bought Friday to watch the movie on Friday. Nevermind the petrol i drove out on Friday and Saturday. You guys are purely pathetic and have no customer service. I WANT MY ****ING REFUND! DONT OVER PROMISE AND UNDER DELIVER.
