Account Locked due to Broken FNB Process!!

I am FURIOUS! Our business banking account has been locked at the time of the month that we do most of our transactions due to our FICA documents apparently being outstanding. For the past year we have been contacted by multiple parties to supply FICA documents (contractors, attorneys, fnb representatives, fnb smses, etc...). We have in each instance emailed all required documents, and also personally gone to different branches a few times taking all of the required documents with and being assured each time that everything has been received, just to get another message a month later, and very recently having our account locked without warning. I have logged a complaint on Hello Peter around this about a month ago, and the reply on Hello Peter was that someone from FNB will be in contact with me (This never happened, surprise, surprise). FNBs FICA process is obviously broken, and this now negatively affects their clients who pays monthly bank charges for this terrible service. If this is not resolved ASAP, we will be closing all of our other business accounts, personal accounts, investment accounts and home loan accounts with FNB shortly!
