Account blocked, Cant access my money

Capitec blocked my account without notifying me, I am musician who earns music writer's royalties annually and now i cannot access my cash. I was at the branch today for hours and the head office asked for a letter which I produced after receiving it from the company that pays me royalties. But then they started having stories and i still could not access my cash. This is unprofessional and very inconvenient, so what impression will i have of Capitec? What message should i share with others about Capitec? Based on this experience? I want my money and for the account to be officially closed, not just blocked...Disappointed!
