What happens If I do not pay PayPal negative balance?

I use to own a Minecraft server, this kid use to play every day. He donated $100. I asked if it was his mums paypal / credit card and he said no. 1 months later he chargedback for "unauthorised payment" Currently its at $340. I can't sleep or think. I need to know what happens, if my parents find out and they need to pay for one I'll feel very guilty. Please, I need answers.

I don't know

So he paid you 100 so that he can play your server? But then he charged you money because he thought that your charging him 100 was unauthorized? I'm not sure if this is what you mean but if you both agreed that he pay 100. Then you need to meet him again face to face. During your meet up face to face, MUST call paypal company and speak to an agent and resolve all of this out. Of course if you know hes hiding something, don't tell him that you're gonna call paypal when you both meet.

If he was not supposed to charge you 340, then tell paypal that. Or if you can't resolve it, tell your parents. They should be able to know what to do

BAD CREDIT.

You can ruin your parents credit if it is attached to their PayPal account. Tell them now instead of lying through your teeth when confronted.
