Hi, I suspect I may have interacted with a scammer but I am not sure. I agreed to sell an item and received an email requesting the tracking number in exchange fro releasing the funds, which was fine, I responded with the tracking number. I received another email asking that I request additional money from the buyer and I could just pay them back. What makes me suspicious is I contacted Paypal by phone and the representative I spoke with claimed not to see the pending transaction even though I can see it on my end. Am I being scammed?
