It will help. They are very good with stuff like that. There is a button where you can report the unauthorised transaction. Do it straight away though because after 4 weeks they can't do anything.
It's authorized transaction without notification, I don't want to waste my time with Paypal, Paypal customer service sucks ass.
They can reply on 1 or 2 weeks, then stopped responding, this is how unprofessional how paypal doesn't have employees.
