The worst bank to do business with

I had a business account with FNB and when I received my first paycheck they blocked my account with the funds in it. They said they suspect ***** on my account. 3 months later my account is still blocked and I am being send from pillar to post. Mo chi Ebrahim is the person in charge of the account and for a full month's I still can't get hold of her. Spoke to Shona K he said he wl get back to me and it's been weeks when I call him he dropped the call. Called and spoke to Bongi Nkose, Porcia Shabalala, Bohlare Vukela they told me that they can't help me with the account. I'm stuck with nobody to help.
