it's only one dude that gave me a bad rating.
He bought an old Direct TV reciever from me. The only thing he was concerned about was..... what type of card is in it. Are you sure it's included, and so on.
So, I sent him the reviever WITH the card. He said it wasn't in their when he got it. He was a scammer. It was obvious to me at the time that he was "changing" the cards to get free service.
anyway, that was forever ago.
