FNB Business falls to provide me with feedback as to why my account is frozen/blocked.

I have recently opened a business account with FNB Business and I am not able to make any payments to suppliers because of my funds have been reserved. I have visited the FNB branch in Protea Glen and 8 hours later I’m unable to work. I can’t make any transactions and nobody from the ***** department has contacted me. I have lost a day of work because of this poor service and terrible customer experience.
