Business account

I recently asked to open a business account and filled forms then sent them via email,they never told me about NCR certificate because I told them I don't have it before they sent those forms. Now they want it and I don't have one right now. I did state that my business Is sole proprietorship but I still can't open the account,how is this resolved? I am really not satisfied because I was told not to worry about certificate now after I sent forms it's now a problem!! I would've opened it using my Capitec app but it seems to have problems via app!! I am really gonna open another bank account if this is how y'all treat your customers
