My paypal account was limited due to someone used it for getting payments in it as donations and i wasn't aware of the account got limited then but when i told them that it wasnt me it got resolved and account being activated limits lifted. But now mt Paypal account balance is 626.96$ but there are 3 payments which are on hold which were 492$.00 98$ 476$ They are asking for charge back what does it means ? charge back means that the amount which were charged to CC holder will be returned back to them or it will be extra amount ? as I am US account holder I don't want paypal to charge my bank account for this plus why would I be charged for something which I did not authorized? Please explain these things will be thankful
