I had a sweater posted on ebay and he sent me an email on ebay saying that he is interested in buying the sweater and told me to text him and I did text him thinking he wanted more pictures or something. I texted him and he said he wanted to buy it but he would send me the payment directly through paypal and I was okay with it as long as I receive the payment first. He said he sent it and I received an email from paypal, it said NOTIFICATION via Paypal and listed the amount and under the email is said that I had to reply to the email with tracking number and after that whenever the shipment said received, Paypal would release the money in 1-3 days after the buyer confirms. The shipment just got delivered today and I know this because I was tracking it through USPS and I texted him saying to confirm but he hasnt replied. After searching the number and his name I noticed this page and now I am scared I have just been scammed for $690.00, what can I do?
