Dispute A

[OctavianSOC]

In the last days I made sold some stuff on a game. That guy that I trade with opened a dispute. Niether him or I have clues that we made those transactions in that game. Whate are the chances to win?

It is a number of 10 transactions. At all of them he opened a dispute, I made them trough family and friends.

Are you the buyer or seller as your post is confusing.

I am the seller

Its against Paypal rules to accept a family / friends payment for selling goods and you risk your Paypal account being limited if you do so.

A buyer would not be able to open a Paypal dispute for 'non-receipt' OR 'not as described' as they would have no Paypal buyer protection.
However they can still open an 'unauthorised transaction' OR do a 'chargeback' (via their card issuer) and you may well lose as you would have no Paypal seller protection.
