Insensitive and reaction/ Highly disappointed

I'm highly disappointed with the way FNB handled my daughter's dispute. She used her card to pay for student accommodation on the 1st of May 2023. The transaction went through on her side and declined on the speed point, she got a text message that the transaction was reversed however,the money did not reflect back on the account, she swiped her card again for the second time hoping that the fist one will come back, well until until today still no reversal happened. She contacted the bank via "secure chat" to check if they can hold/ reverse one transaction. She was told to log a dispute that might take 7-30 days. She is now stranded in a foreign country with no money and the bank doesn't seem to really care about that. I've been a loyal FNB Client for over 15 and have never been so dissatisfied.
