Welcome to Android Central. Not be over critical but I'm having a difficult time following you on this. I can't tell where one sentence ends and the next starts and I'm pretty sure there are missing words too.
I did get that you said gift cards and that is an instant red flag. No real legit company needs you to pay by gift card, unless it is theirs. Are these gift cards for or from the business in question? Then it is most like a scam.
I still cannot figure out how Paypal plays into this, were you trying to make a purchase, where you trying to send or receive money? It might help if we had more of the story. But like I mentioned before gift cards are a scam, any web search will yield the same response. Don't do it and report the company, email or whomever is trying to get you to pay this way.
Let us know what you find or if you want to offer more information.
