FNB POOR SERVICE..........NX!!!

I'm very much frustrated with the level of service I've been receiving from FNB. On the 17th/12/2021 using my FNB App I sent money to an inactive FNB Card. It was my sisters credit card and she finished paying for it in 2017. She doesn't have it anymore.

I've completed REVERSAL FORMS, DEBITCARDDISPUTE FORM, DIGITALRECALL, TAKEN LEAVE OFF WORK, SPENT MORE THAN 6 HOURS, CALLED MANY TIMES trying to sort this but I'm not getting any assistance. it's been over a month now. I've been using FNB for more than 20 years now but i must say..........FNB doesn't know what they are doing. no one seems to know.
