Business Account Frozen without any warning

I opened my business trust account Jan 2013. I supp**** all relevant FICA doc which were scanned in by Heidelberg GP Branch. In Aug 2014 I rec an email from Mr S Pather [Email Removed] asking for all relevant FICA doc to be sent again to them.<br> I sent relevant documents to email address in Sep '14. (3 emails I have proof ). He rep**** he received everything and they would call me should they need more papers.I haven't heard anything again from any FNB employer again. Yesterday (4 March 2015) I rec sms that my account is frozen and that I must call *** with ref ***0. I did and the guy took my info and email address and said someone will contact me to say what they need. He gave me an email address [Email Removed] to forward all documents again. I fwd all 3 emails to this email address and explained the situation. All I could see is that the emails were read, no ph call or reply. I phoned the 087 number again this morning and a Pumzile took down my info and said someone will phone me...still no reply. I ph my branch and spoke to Yota at Heidelberg. She emailed complaint dept. I can't do any business. No warning or ph call from FNB that they still need info..
