I'm not even sure that was a 600.00 bass.
A Fender bass is going to have a serial number somewhere and this thing as pictured doesn't have one on the front of headstock, back of headstock or on the neck plate. Also, where did you find the CIJ sticker? because it isn't on any of these pictures. you can see the entire front and back of the headstock. I'm not sure this is even a Fender made bass of any kind. I would certainly send these photos to Fender's customer service and ask them about it. I would pull the neck and get some shots of the inside there as well just for proof.
I have sold on Ebay plenty of times, even made a living doing it for a few years (I collect and sell vintage vinyl records). I quit because the seller can not win any battles, not that I was ripping anyone off, but that game works both ways. because I was a power seller, I got all kinds of advertising from companies of varying foreign locations wanting to sell me bags, shoes, clothes, jerseys, and yes Gibson and Fender guitars and basses. All sorts of other cheap knock-off stuff. EBay is rampant with this crap. I hope you get satisfaction and I'm positive you will. Next time though, make sure you ask for a serial number and a picture of it ON THE BASS.
Good Luck
