No money and no order!

On the 6th of March I visited KFC kokstad, I attempted to make use of the self service counter and upon noticing that it was very slow to respond I approached the till to make my order. After my order was placed I then used the tap feature on my phone and the transaction went through and money was deducted on my account. The person assisting me with my order said it had declined and I should tap again because the store was having network issues. I refused after he kept insisting that I should tap again. He then called his Supervisor who made it my fault that the transaction had failed. I walked out the store without my order and without my money. The supervisor said she would call me it’s now the 16th And I have not received my money back. I have spoken with my bank and they say I have to wait for kfc to claim the funds because the transaction doesn’t appear on my bank statement. Highly disappointing how their team has handled this situation. I have communicated with them on numerous occasions to tell them that I cannot provide a bank statement as the transaction doesn’t appear on my statement however I have the sms to show that the transaction did occur and funds were deducted from my account.
