30 day investigation but still can’t reveal what happened to my money

@FNB bank, how do you guys investigate a case of a transaction that went off but unable to tell me which stores my card bought at and it bought, I reported the incident within minutes of it happening. What did you as FNB to protect me as a client, we’re you not suppose to freeze that transaction? How do you not have info on what was bought, how was it delivered to the person but you have been investigating for a month. How is it that for an entire month I am the calling you guys to get any sort of feedback, getting sent from pillar to post with no one to account, and apparently your investigators don’t speak to clients. Who is suppose to have answers to my questions? How do I loose money in your house and you have nothing to say about it, after 13 years of banking with FNB I need to beg you guys to tell me what happened to my money, I have to waste my airtime calling you guys and spend hours holding until eventually I take time off work to come sit at the branch and still not get any assistance. It can not be that I report a ********** activity and you investigate only to tell me that FNB was not involved, what did you do for me as your client to try and resolve the issue? Such a traumatising event to have happened to a person and the people responsible for safekeeping your money can not even afford you the courtesy of a phonecall
