Millennium BCP - Discrimination in account opening and ignorance

I have been a long term customer at the bank of Millennium bcp in Caldas Da Rainha. I never gave them any problems as I am tech savvy and always use the bank’s app. Last week I went to Millenium BCP branch near Praca Da Fruta in Caldas and asked to open a bank account for my business that I just registered. We are three partners 2 people are from Nepal and I am Indian. Therefore, we gave our passports and residency, however, one of the partners is new here so, he doesn’t have a bank account yet but has everyright to stay and do business in Portugal. Hence, there should be no problem in opening a business account as two of the partners already have bank accounts and all three are legal business owners. But the bank employees took copies of our documents and told us that he will need to ask for an approval from the headquarters or something similar. It’s already been a week and every time we go there, he ignores us and starts doing something else other then attending us. When we approached him, he said he will call us in two hours and it has again been two days. I don’t understand the problem behind this ignorance and delay as every paper we submitted is legal and we have done everything through proper channels and lawyers. It seems to be a bit racist to seek approval for our account just because we are not natives, we are all legal here and doing business with high investments.
