Long story short
(1) I was selling a whole bunch of rare and complete SNES and Sega Genesis/CD games and systems from my collection.
(2) One Ebayer purchased 15 items worth $3,600 from me (games & system such as Snatcher, Dracula X, Sega CDX, boxed mini SNES etc)
(3) That Ebayer is located in Sacramento CA, about 3 hrs away from San Francisco.
(4) He obtained my phone number via the Ebay system, then we scheduled a local pick up in Davis, CA where is 1 hr from Sacramento; 2 hrs from SF). He paid me via Paypal before we met.
(5) I met with him in front of a Safeway store, gave him all the games and had him signed a contract. The next day, I also sent him a replacement game via First Class Mail as I forgot to mention some flaw of one of the games.
(6) A week later, he filed a chargeback on Paypal claiming "items not received/delivered". He perfectly knows that I could not provide a tracking number.
(7) The replacement package was returned as his address is "undeliverable"
(8) I explained the whole thing to Paypal (including his fake registered address and he got my phone no from Ebay) but paypal still rules in his favor.
(9) I immediately filed a police report in Davis, file a report with the San Francisco District Attorney's Consumer Protection Office and filed a report at the IC3 (internet crime report by FBI). I also closed all my credit card and bank account linked to Paypal.
(10) Paypal could not recover all $3,600 from my account so they sent my account to collection agency.
