VERY DISSAPOINTED

On the 17th September 2023, I went to Nando's Meyersdal to buy a meal. Just as I was paying using a bank card, their system went "offline". The money went out from my account but they said they can't pick it up from their side. I had to wait for more than 20 minutes while they check and they still said they can't trace the payment. They said that I need tp pay again in order for them to release my order and they said maybe the then the transaction will be reversed same time but it didn't. So basically I paid twice for one meal. I waited and waited for the reversal but nothing came through. I left and was told that they will call me the following day to check if the reversal took place. Indeed they called me in the afternoon the next day and I told them that I still have not received my money. They called again the following day and I told them that I have not received anything. They then said that I need to come through with my bank statement so that they can check. So I asked them that they expect me to drive all the way to them using my petrol to be refunded almost the same amount I will spend on the road?

Today is the 25th and I still have not received my money. I am very disappointed and annoyed actually. I just want my money!
