Sorry, but I do not understand what it is you are asking about. When you purchase an iTunes Card, you redeem it to your own Apple/iTunes account. You don't give it to a "vendor".
Best,

Again, not sure what it is you are describing. You cannot use an iTunes or Apple Gift card for anything except an Apple account. You cannot exchange an Apple or iTunes Gift card for cash, bitcoin, or anything else. It can only be used to put a credit on an Apple Account.

I just want to check the used details of my gift card
Again, no clue what you mean? You purchased an Apple Gift Card or an iTunes Gift Card (which)? Then what did you do?

I have a vender in paxful.com to make an exchange for bitcoin
So he told me it’s been used up, I know it’s. A big lie, I need the used details
I need an answer from the Apple team not you
I gave a vendor my iTunes card on paxful. He told me the card was used which I'm sure is a big lie. Please I kindly need to verify this
