Almost 70year old hit with card ***** with no answers.

Unsure how this is even possible. So, Friday night we all were sitting outside between 8 and 10pm, (my soon to be 70year old fathers phone was OFF on the counter in the house) Saturday Morning when he turned his phone on, he was greeted with a incontact message on the fnb app, "R569.79 reserved for purchase @ Ubertrip Help.uber" with his card ending 8197. (27 September 20:26) Never ever has he ever used his card for any online purchase, nor was there any acceptance of any purchase via his app. He only uses his card once a month, and that was this friday he made a withdrawal as usual only at a FNB ATM (KNYSNA BRANCH ATM). First thing he asks me how this is possible? I imediately helped him and reported the transaction as ***** on the FNB app, thereafter the card was cancelled (his only card) and a new one was ordered. No further communucation whatsoever and the money has not as yet been reversed still shows in a pending state. I ask that you investigate and reverse this transaction with urgency as this is clear that older clients are targeted with *****. Who ever made this purchase must have some sort of way of being tracked. I just dont understand how any purchase is able to go off his card without him ever using his card online ever, nor instores either, other that at an FNB atms, and without him "accepting a transaction on the fnb app". He has now been left with R52 in his bank account due to this and that was his last money, a elderly unhealthy old man that earns a small monthly salary and still needs to work. I ask that you sort this out with urgency. Thank you.
