You need to report this.
Straight up.
No minor can be held responsible for a debt and it sounds like identity theft.
OR someone trying to get info so they CAN steal identity based on info given.
You have to be very careful these days.
This happened to me.
I responded by asking as many questions back as I was being asked.
What is the name of your company?
What is your name? Your title? Your extension?
What is the name, title and phone number for your supervisor?
What is your physical address?
What is the account number you are asking about?
SAY, "I need to write all this down so I can get back to you."
When you do that, chances are, they will hang up on you if they aren't legitimate.
If they are legitimate and they will give you that info WITHOUT YOU giving any information, you can report what they tell you regarding identity theft.
You can also contact your local law enforcement agency because many times people will target people in a certain area.
Either way, you know a young child is not responsible financially no matter what their parents do.
Fire off questions and let them know you're writing it down.
Report it.
Sorry and best wishes.
OMG!
Just saw your update.
NEVER assume it's not possible for identity theft.
I've worked in insurance and at a hospital and you would faint if you knew how many people use SS numbers for people who are dead let alone minors. I've seen it happen when people are trying to get medical care under a different social security number.
It really does happen. Don't assume it can't.
