FNB is disappointing

I had a problem of my account being debited these small amounts that didn’t clock every now and then ,it was brought to my attention when I was in Pretoria and I apparently purchased at Pnp Tzaneen , I went to FNB in sunny park to have it checked out, I filled in a form , that had a list of all the transactions that had took place which I think were close to 18 and till this day nobody has gotten back to me to tell me what happened to my money ,I believe a bank is meant to protect peoples money but in my case FNB has been *****ing mine , I’ve got Uber transactions that are default and I went the extra mile of getting a new card but still FNB has not bothered to email or call me and give me at least some sort of feed back , I am highly disappointed in how you treat clients , I may not be a private client but I do deserve to get answers when I seek for help, it is really disappointing to see how nobody has bothered given that this was done on the 2nd of January , wow FNB!!!!
