Mc Donald's taking my money and not giving my order or receipt

on Saturday 08/05/2021 i went to Mcdonalds at Westgate mall Mitchells plain, i was then advised by one of their staff members to put my order through on 1 of their machines and selected my pay option to be via Card, i instert my card details and the notification immediately went off on my phone saying that the payment was successful but the machine had an error saying that it is an EFT error. I then proceeded to escalate the issue to the staff. The store manager then advised me that they cannot do anything about this because they did not receive my order in the kitchen even though i showed her proof of the payment that went off on my account. I then asked if they can escalate it higher as i felt that this was horrible customer service and just telling me that they can't to anything about it...i Spoke to a Branch manager called Mogamat that told me that he cannot do anything about this as the problem is with the technology of today and proceeded to say he cant offer me anything even though it is their equipment. Mogamat then told me that i need to wait 24 hours to see of the money reverses back into my account and if not to go to the back and get a bank statement then bring the bank statement back to the store and that statement will have to be forwarded through to Mcdonalds head office which means that i wouldnt off been able to get the money right away either also because it was a Sunday the next day the banks was obviously closed. It is Now Monday and i still haven't recieved my money back, i am at work not having the time to even get to the bank for the statement and i am unsure as to how i will be able to get this issue resolved when all they could have done was give me my meal for the least for the inconvenience that they have caused but no, you guys just left it to the customer to solve on her own
