Worst bank ever

What customer service???

FNB decided to make one of my accounts dormant (the linked account with my minor son's savings money). Without any notification to me. They have now taken ownership of the money in the account, and refuse to give me access to my account and my son's money.

To get the money back they insist that I go into a branch to verify myself. WHY? The account was linked to my banking profile (that still exists and is active, with other accounts that I'm using).

I keep insisting that they simply add the account back to my profile so that I can access my funds. They refuse. They stole quite a few bucks from us.
