Disappointed Client

I had an account with African Bank and someday they froze my account told me I was involved in *****ulent activities and I went to the nearest branch they told me I received money without a reference I was asked to provide a bank statement from my other account I did that they said they would call me and for 2 years I waited I only became aware again about this when I found out my ID has been listen on SAFPS and I can't get a loan I can't get credit. I called them again they said I must wait for a month it's been 2 months still no feedback from them and this is really frustrating and causing me grief.
