Bad Attitude and contempt towards foreigners

I went to FNB Woodmead to open an account for my cousin on Saturday 14th March 2015. A consultant by the name Bradley David kept on referring to us as foreign nationals who had no rights. First we gave him a passport which had a valid work permit after going through the pages of the passport he said there is no work permit. We showed him the work permit. Next he said you came come next week, Next he said we need to personally apply to the reserve bank of South Africa for permission to open a current account. Next he refused our proof of address which was in my name saying you too are a foreign national and you are not allowed to sign that proof of address for another foreigner he suggested we find a South African citizen. At that I asked that he gives us back our documents as FNB is not the only banking institution in the land. I want to know if this is FNB's official policy to look down on and harass prospective foreigners who want to bank with them. After all this we went to Standard Bank and our application was processed without any problem
