Went through the same thing this month (since late last month). Only they shipped a pen or pencil shaped object to a nearby house which happened to be vacant. It was supposed to be a metal detector - F75. USPS brought it over, I took pictures and refused it / RTS.
Ebay closed the case in the seller's favor despite them never responding and the package being refused. Their feedback was good, but sketchy listings around the time I ordered. Account must have been compromised.
Finally got the money back with a police report and appeal... but get this, since the case was originally closed in seller's favor, my negative feedback was never posted to the account, so they can technically still defraud people. Not good at all. Posted on the ebay community.
