FNB - uncalled for account to be frozen due to FICA

Apparently FNB froze my personal account , being unable to transact and use debit cards on it, all because.... they did not get my FICA details updated. So I called FNB, lady on phone asked me for my cell no and physical address. After supplying this she said it was updated and account active..lol. She said FNB had sent me an sms on 16/1/2023 requesting FICA docs, then on the 17/1/2023 they froze my account after being an account holder including my business's for over 50 years !! Hows that. Nobody from FNB could call me for just 2 mins to get these details over the phone?? That is poorest service attitude I've ever had. Want to move my business and personal accounts to another bank, does anyone have any suggestions. Don't want to move from bad to worse. Big business's too say that FNB does not respond well and dont care that you move on because they are so big
