FNB hold Issue

Hello I have been a loyal individual costumer, without a business in FNB. Recently an error comes my way and says that I should call for assistance for inter-transfer aco****s within my own accounts. The seem to have put my account on hold and they do not seem to help me to retrieve it and resume with my payments, subscriptions and itunes. What do I do?

They claim there has been a ****, when there does not seem to be one. How do I proceed? Please advise :)
