FRUSTRATED, DISAPPOINTED CUSTOMER

This morning , I recieved an message from Fnb threatening to freeze my account if I didn't update information for my account. The message then told me to either visit a branch or call the helpdesk within 5 days. I am very angry at this because this is very very short notice, I am highly disappointed because FNB is asking me to verify information that I verified not so long ago. Is this for real FNB or is it just a **** ??!
