I cancelled the invite you sent. If you invite a random MM, no one else can claim.
Some games have very poor account management systems that have major flaws allowing the previous owner to very quickly recover an account. This creates a condition where those games have a much higher scam rate than other games.
Many MM do not claim transactions for those games for this reason, as they do not want to be involved in a dispute.
If no one claims by the end of the day, I recommend cancelling the transaction and using TG free version instead.
