paypal dispute

Hello guys, sorry for wrong place to post this, but I got one question, I did a boost to one guy in another forum, he paid me with paypal first, but when I finished the boost, he is trying to get his money back, he paid me as friends/family, what should I do ?
Thx.

If you got paid with Family and friends he cant get it back.
If you finished Boost to what the customer bought then dont do anything.

Report him to riot so they delete his rewards :)

but should I answer him ? or dont do it and just wait and see what paypal do ?

If he gets his money after F&F transaction there is no way to do anything with it since it would mean an unauthorized transaction claim.
