FNB account on hold, no warning or explanation

I’m extremely disappointed in FNB, my account was put on hold due to outstanding documentation that I sent several times, the first two times I was contacted and told what was missing, I sent them again with that they wanted and nothing was said, so obviously I’m going to assume everything is in order since they kept calling and emailing when something was missing. Now I find out my account is on hold, no communication was sent, I learnt this through googling why I wasn’t able to withdraw or make any purchases. No word or response, I’ve sent several emails with updated details and still the KYC error persists. I hardly have time to go into a branch, I’m disappointed and angry.
