Fnb worse bank ever

My account has been placed on hold due to complaints been made by customers and alleged *****elant activities for a long time now every time I am requested to pricide supporting evidence and I provide it something else is always needed I was not even provided with a case number I have issues with 2 investigators.. Mr John volmink he always answers his phone and does not give me clear information on what's going on.. He asks me to provide certain information and gives me the nod that he will finalize with this information but it never happens he will never call me and tell me wat I need to do until I call him there's always something else missing then this morning after waiting for a very long time he answers soon as I greet him he hears its me and just says hel call me back and hung up... Then nomthandazo macayi who emailed me on 25th October stating she placed my account on hold due to a complaint she had received which I appreciated I was asked for supporting documents.. Then I had resolved the issue and the client provided and affidavit that our issue has been resolved and he wants to withdraw the complaint he went via the branch and submitted this affidavit still till now I'm unable to get a hold of Ms macayi she never picks up respond to emails or is ever at her desk coincidentally her reporting team leader is also never at her desk I'm at wits end I understand they have a process atleast tell me what's going on I'm in a very bad situation
