After winning I received a message in broken english asking for the IMEI number of the phone. I refused and told him he was protected by the ebay buyers policy if he wasn't happy with his purchase. He then sent me a harsh reply saying I had to give him the IMEI number. Then he accused me of trying to sell a locked phone. He then sent me another reply saying I don't trust him so he doesn't trust me.
So I offered to cancel the transaction. He told me to go ahead and cancel.
Before I could cancel he sent me another reply saying he decided to trust me and asked me to please send him the phone in a small box. He made the small box request twice.
He sent me the payment and then I googled his address and realized it was associated with fraudulent purchases so I refunded the money.
He sent me a message saying: Why did you cancel the transaction? Why?
