That's what you get from buying shit on Ebay.
I buy shit off eBay religiously almost, though this was my first used console purchase.
Very much this.
I bought an Xbox Elite pre-owned off Game's website, when it arrived and set up etc, the Xbox had been banned offline due to people modding it.
When I took it to the store they took it apart and saw where they messed with it.
Wow, that's some shit luck man, but you could have sued them, that was an actual form of false advertising if they mentioned nothing about it being modded.
Edit: Never mind the previous owner was at fault not the store.
As for me, considering this is a blu-ray drive issue, I don't put blame on the seller, but I'm not cutting them any slack either. It could have just as easily been knocked a loose due to shipping. The box came like it got it's ass beat in a fight.
