FNB enterprise banking blocked my account second time

This is the second time FNB has blocked me from using my business back account. The first time this happen they blocked me and I couldn't use my business banking FNB online enterprise banking. We send in the document. So FNB went over to a new system and it happened again. How can a business own to business like this. How can FNB just block a business owner on their own account and I can't use my business money to do business. This is my company money FNB Enterprise Business Banking not yours. I am done and will go to the nexts back. I refuse to let a bank hold my money hostage! Unexpectebale! I would advise anyone who does business with FNB to stop and look for better options.
