i just got scammed trying to convert an amazon gift card to bitcoin via paxful . It was my first time, i had no idea how to trade safely . i did not read the guide lines well enough

i got scammed on paxful after giving an amazon gift card to someone in exchange for bitcoin. After he redeemed the card, he told me that i should cancel the transaction because the card wasn't mine and he won't be able to redeem the card because it was purchased using a credit card, only for me to find out later on that the card was already redeemed. I tried writing the guy but he had already blocked me
