I had a savings account with FNB and apparently it was freezed due to outstanding FICA documents en one day when I logged into banking app the account wasn't even appearing anymore. Then after few months I went to FNB Klerksdorp with required documents so that my account could be reactivated, then I was helped by the lady who managed to reactivate the account en I asked her about the money which was in my account which was roughly R418 at the time the account was freezed. Then the consultant filled a claim form in and I signed. Then she submitted the form and told me that the bank will refund me but till today I haven't got my money en is about 4 months now. I still want that refund.
