Blocking business

I received a sms on 6 March requesting FICA documentation. On 6 March I sent an email to my banker at Montana Branch. I asked a list of the required documents. I received no reply from her and visited the branch on 15 March to find out which documents were required. I met with the branch manager and the banker. They gave me a list and I sent the documents to the banker on 16 March and again on 23 March. I discovered on 3 April that the account is blocked and phoned the branch manager. She promised it would be attended to. She also confirmed that all the documents were send to the FICA department. I phoned her again on 4 March, and she said it will be attended to. As of today 10 April the account is still blocked. I am considering moving all my accounts (5 business accounts) to another bank.
