Did I get ripped?

[WVMTNBIKER]

I won a cargo cover for my '03 X5 3.0i, build date 8/03. A guy had it on ebay, I made him an offer, he agreed and I purchased via Paypal OFF auction i.e. for goods purchased.
He stated it was OEM and fit models '01-'03 X5's. It was in my color and is in like new condition.
However, it does NOT fit. I went to realoem.com and the part number they give based on my VIN does not match anything that's on the cover itself. It will not begin to fit my vehicle as the attachment points are all wrong.
It appears that it should slide in a groove into place and snaps into the bracket lock. What I got is physically impossible to lock into place. On my vehicle, the portion that is molded into the body trim has a divider that the brackets of the cover slide over and lock onto.
This cover's brackets are solid and have NO provision of a "divider groove" to fit over.
I hope he will refund my money since it was not though eBay and I have no protection. Hmmm, maybe that's why he sold it to me so reasonable? We'll see I guess.
Any ideas of where to get the part numbers off this cover? I found a paper tag with 11 digits but it does not match realoem.com as a valid part number. I will keep you updated but any help w/regard to the above would be great.

Here is the parts breakdown from realoem.com based on my VIN:

This shows TWO covers? Am I missing something here? The cover I got looks like the one on top or the larger of the two. Note the end brackets on the bottom one-they match more closely my bracket holders. But the cover I got has the end brackets that look just like the ones on the upper picture cover. Geez, can this be that hard? Does it take BOTH covers to make this work? My X5 has the electric seat backs that move forward/rearward as needed. Does this help? Anyone got any pics that would show me more detail than this parts diagram? Maybe I'm missing something here again???????????
