ebay outsiders

I’m scared.

I ‘sold’ a pair of shoes on eBay to a seller from the US. Turns out he’s actually from Nigeria, doesn’t want me to declare the value of the item (they are quite pricey), has alternative addresses and has contacted me outside of eBay. He also, said he has paid me but Paypal and eBay are not showing payments. Worse, I’m getting emails claiming to be from Paypal and eBay that will not authenticate themselves. I haven’t shipped the shoes. I won’t. 

Now I’m getting threatening emails, saying that I’m ruining the ebay community. Now this person who is obviously shady and dodgy knows my name, my home address and my e-mail.

My birthday is tomorrow on the 21st, I’m on the verge of tears that this is actually happening to me.
