Lack of communication, shocking service, frozen account!

Shocking service from FNB !! After only 2 days of warning by sms (only) that I need to send FICA docs (with zero description of what those should be) my account was frozen. Can't pay for anything! I'm appalled at this lack of communication from FNB ... no one has called me or emailed me, not even a notification on my app to request the docs. Now, after 2 days of notice, I have to run around trying to gather these unknown docs during an extremely busy week for me... extremely disappointed!!! Especially since I've been a paying customer for the past 30 years!
