Digital Game Code Account Sellers Fraud

Guys, Please be careful of buying digital codes online.
This is a The worst kind of method to buy games,
I previously fell in to this via carousell. After a few months the original accounts were deleted. The seller gave me some Hong Kong Account and after a while he was MIA even after I've made my PSN account as the primary account to play those games. All the games that I've bought are locked now. Can't be played.

Please report and don't buy If you've encountered this.
