Fnb ***** department

First of all my account was blocked without my knowledge or consent. When I went to the branch is when I found out about the ***** case against my account.but they cannot specify was is ********** about the matter. I was then told it will be resolved in 10 business days n yet no contact except for a unclear call came through that I couldn't hear yet they are now claiming that I did not pick up the call this is so ********* and wrong.
