Frozen account

I tried to log into my online banking only to get a response that i doubt have an account. I phoned standard bank to find out what is going on and they informed me my account has been frozen due to FICA. They wanted to know if i got any correspondence from them to which i said no! The only correspondence i get from standard Bank is my statements. She informed me that i need to FICA my account by going to my branch with my ID and proof of residence. When i owned this account my i already did all this 2 years ago. Now i am sitting in the bank waiting 45 min getting the worst service. I do not have this problem with FNB whatsoever!
