Nedbank is for personal banking not business.. PERIOD,,,,..!

I opened a business account with Nedbank and paid R500 to activate it. A month later I later I amended the details of the company and app**** for a new business card, they charged me a fee and opened a new business card with the old business details, after finishing the funds in the account they sent me a message that the account was in arrears with R-18 and I should make payment immediately or they will close the account, I transfered R20 to the account and they took the R20 and closed it anyway.
