Business account frozen - no feedback from bank

I was asked to submit documents for FICA and have submitted the required documents. Also called them on the 25th to make sure that my account is ok, it was still being investigated and today I tried to make payments from my account and now it is frozen. Cannot make payments and this is affecting my credit scoring, really disappointed. The lady at the call centre told me today the same thing as last week, that someone will contact me and assist me, nothing has happened in a week.
