FNB - How can we trash you?

FNB has frozen my account because they suspect someone used my account number with their name for their salary to be paid into my account. This could be a person's finger error because I don't understand why a person would want their salary to be paid into someone else's account. That person has not put or taken money out of my account but I I am being frustrated with the inconvenience because FNB doesn't care. I am highly inconvenienced by this sick act and they don't even communicate with me. I found out when I wanted to transact and when I call and email to follow up there's no response whatsoever. This is my last FNB review as they have been nothing but a pain throughout my business with them. I am forced to closed all my accounts and move to another bank because of the sick incompetence of FNB. I can never wish anyone to go through this FNB hell.
