Fraud

Description

I just want to make sure I’m emailing PayPal and not getting scammed. I recently am selling an item for $100 and the man who wants this bag wants to sell it to his cousin for a birthday present. He wants me to pay $300 extra for a eBay gift card for her. I did this but PayPal made an error and put $1000 instead of $500 he was going to give me. I needed to get an extra $500 eBay gift card for PayPal to credit me. I then needed to upgrade my account, did that, and now I need to spend another $500 in an eBay gift card for PayPal to upgrade my account and PayPal will credit me for $1,500. Is this okay or is it fraudulent?
