I got ****med

I have been a regular loyal customer at Seattle Coffee Co. FLM Tokai since 2020, I always buy more than one drink. I have been happy with their service and hospitality hence whenever I go buy, I would give a tip not less than R10. Yesterday I went to buy 2 seattle freeze drinks and took my free drink with, it all amounted to R79 + R10 tip. I paid my R89, it went off from my account but they didn't get a receipt from their side. I was asked to pay again because the payment did not go through, I wanted to understand what was gonna happen to the R89 that went off from my account (I even showed them the proof from my banking app), If I must now pay again for the same drinks. Bruno printed out the cash receipt to check the transactions, he then told me that I must wait because the money will be reversed back into my account. He told me that he cannot give me cash because they will have a shortage when they cash in later, he told me he will see later if they have extra money when they cash in. He told me to come back the following day if the money didn't reflect into my account. I paid again R79 for the same drinks and left after waiting for 20min , even pass my lunch time. This morning I checked my banking app, the money didn't come through. I went to seattle Tokai to follow up on the matter, only for me to get there and be told that Bruno is off today and tomorrow. That really got me ****ed because I got played, he knew that he was gonna be off today and tomorrow and on weekends I am not this side of the town. Now I got ****med because I don't understand how am I made to pay for a company's system error which wasn't my fault and I have no access to. i am deeply disapointed about how this matter was handled, all that he was worried about was his cash in at the end of the business day and not worried about me loosing money to them.
