you can try contacting paypal and saying them you were scammed
I would recommend you not to do that, just say that your account was hacked (or something like this).
PP usually is not willing to refund if you've sent your money by yourself.
i send the amount using friends & family.
just forget about it, small amount.
the amount can be low still being his money and being robbed by someone is not something that can be accepted, if it were in real life the thief would already be in prison
OP try to get in touch with paypal and explain your situation, you must tell the truth to paypal so that they help you, show all evidence that you have
