Poor customer service

I came to get a card and waited 2 hours in the queue until I was served. I was patient as I know this is part of covid protocol. The teller who assisted me gave me a card and a pin. When i used the atm, it retained my card and said the pin was invalid. I went back to the teller. She gave me a new one which also got retained as invalid pin. She then said i must come back tmro as she doesn't know anything about the banking system. After 3 hours, I am being dismissed nonchalantly like my time isnt valuable. If I had arrived just before the bank closed I would have understood being turned back. But after a 3hour wait to be dismissed and told to just come again without any guarantee of whether the problem will be solved is unacceptable. I am also a full time employee and took time out to go to the bank to receive such an unpleasant experience. I will be closing this account
