Capitec Business APP

I almost slammed my phone against the wall because of their business app that keep rejecting username and passwords. I selected "forgot password" create a new one, back to login page and still says "username or password is invalid" I went to their online page to log in from there and it does the same thing there also. Now i miss FNB, i need to use this account as i just opened it changing from fnb but now I cant have access to it.
