Poor Service FNB from FNB business division client centre

I contacted FNB business call centre to close the account. The guy couldn't help me because I forgot the name putted on the application online, even after verifying all other data required. He then referred me to go to the bank. There are so many ways you can verify if its a correct hard holder. I think he didn't want to assist. Yes sometimes what we put online application we forget. That's why they ask several questions to be sure.
