Three weeks trying to open an account

I have submitted all the required documents in order to open a business account and it's still not done. Every time I call for an update I hear a different story, today I was told I must submit a copy of my id and company registration which I sent over two weeks ago and they confirmed they received it. Last week Friday they called to tell me they have everything besides a valid proof of residence which I sent on Friday but today they don't have any of the documents submitted. Again all FNB does it to respond and say \we are attending to your complaint"weeks later still no response. FNB is loosing it"
