No Booking Confirmation for Movie Tickets

On the 2nd of April, I booked four tickets online for Avengers Endgame. These tickets came to a total of R344.00. The money was taken from my account but I received no booking confirmation email. This wasnt the first time I booked online, so I knew i should've immediately received a confirmation email. I waited a day and nothing came. The app also said that I had made no purchases. I went to Ster-Kinekor Tygervalley and they said I should wait till the weekend as their servers were down. I came back a week later, still having received no confirmation, and tried to get help. The manager said I would be refunded but that I had to personnally contact customer care and send them a bank statement along with my details. I did this amd received a generic email from Ster-Kinekor saying that an employee would contact me. The next day they requested that I send my bank statement and details and I did so, even though I had already sent it the day before. It has been 6 days no and I have not received any reply from Ster-Kinekor. I have been emailing them every day with no response, not even a "we will get back to you shortly". I have been more than patient, but I need to be refunded by the end of the week. The movie date is approaching (30 April) and I have no idea whether my friends and I will have the tickets I paid for. I don't usually write reviews, but this is my last resort. I need to be recompensated for my troubles as it's not my fault that Ster-Kinekor's servers crashed. Please give me any advice that you have with regards to this matter.
