Ebay tracking says item was delivered but I didn't get anything?

I bought a iPhone case about 3 weeks ago and just today I checked the tracking number, since it was supposed to arrive around a week ago. It says the case was delivered (Sep-10-12, 09:56 AM) but I didn't get anything? Also, the mail man NEVER comes that early. He's always here around 2:00-3:30PM. So how was it delivered around 9:56 apparently? I contacted the seller, but now that I look back I realized I sound like i'm trying to get my money back for something I received. I don't want to look like a scammer. What should I do? I asked my mom about it and if she got anything in the mail and she said the only thing she got was nintendo DSi games for my little brother, and some other envelopes. The case was only $2.80, but still.

Added (1). 9:56? Thats nearly impossible. The mail is always here before 4:00.

I'm pretty sure that it means that it was just sent today at 9:56 A. M. Not that you should receive it today by 9:56. I'm guessing you should just wait a couple of days then maybe contact customer service for e-bay.

Call the post office and ask them. Give them the tracking number saying they are showing it as delivered but you have not received it and ask them for proof of delivery
