Transaction ID : 22f08d4e-f5f4-4659-91d6-da932f23af72
From the start i send to him a invalid amazon gift card because the code in physical gift card isnt clear enough to see , after that i get another card with clear picture and send to him , he told me this card is invalid again ! It is impossible because the card is clear , i already checked letter by letter 
He is very dump when send a fake screenshot about invalid code then i checked the code on my account , its say " this gift card is already redeemed into another account "
His evidence betrayed himself 
@DunnBiscuit please take a look and ban this scammer .
Thanks a lot ,
Best regards.
