FNB IS THE MOST *********** BANK

I have a business account with FNB and they have changed signatories without any authorization. I am now unable to do any payments such as suppliers, wages etc because of a "mistake" on their end. They cannot even give me any information pertaining to my own account (THAT I HAVE OPENED) and all they say is "sorry for the inconvenience". It is already such a mission to get hold of call center,and when you finally do they cant assist. I would never EVER EVER EVER EVER EVER recommend FNB to anyone as they are extremely *********** and I will be closing my business account as soon as I able to access my account. It takes 48 hours for them to get back to me so if I do not hear anything I will be writing another review. Everyone is working from home so there isn't even a way to speak to someone in management. I should not have to pay the price as a customer for their staffs mistakes, this is NOT ONLY INCONVENIENT, I WILL HAVE TO PAY INTEREST ON LATE PAYMENT. FNB IS ACTUALLY BY FAR THE WORST BANK I HAVE EVER DEALT WITH. THEY ARE NOT GOOD FOR BUSINESS. I WILL ALSO BE CONTACTING THE BANK OMBUDSMAN !!!!!!!!!!!!!!!!!!!!!!!!!!!! THIS TYPE OF ERROR SHOULD NOT HAVE BEEN MADE.
