Constant fica submission

I opened a gold cheque account 13th April where I had to give FICA documents ofcourse. Then to receive my cheque card I ad to give the courier fica documents (fair enough). I receive an sms on the 15th May saying that FNB will freeze my account if i dont submit FICA at the branch. I called the call centre (Didnt get a name) the woman was very rude and did not give me an explanation to why I have to give FICA for a 3rd time. I dont understand why I have to give FICA documents for a 3rd time. FNB advertise that it is so easy to change banks, this is completely untrue. I have had many admin issues from FNB from the start.
