Refund

I did an online purchase on the 8th of July for tickets and popcorn however the system crashed and error was given however my funds was taken, I called the Centre she said I will get my money within 48 hours. I then had to rebook and pay from another bank. Up till this day I have not gotten my money they make me run around like a chicken for 280r.for a big business like this, this is unprofessional and absolutely dissapointing. I have sent both bank statements, I send emails and get replies after a while. I want this escalated and I want my refund ASAP I don't care if it's 10r or 1000r it's the principle of the customer service which is dissatisfying
