You don't come first at FNB

Without communicating properly FNB freezes my accounts on a Friday afternoon to make it as inconvenient as possible. They claim to have sent me an email i.r.o. CRS and tax liabilities on 18/12/18. I have no record of that. About a week before they freeze the account some ***** sms's were sent, but as they resemble phishing attempts they were deleted. Then they freeze the account. Their call centres experience high call volumes, so no way of finding out what is going on. Trying to find out who or which department is responsible for this mess doesn't yield any results. What a way to treat your (soon ex) customers
