Gears of War Boo

I finished Gears of War and I decided not to play Gears 2 right away because the first gave me headaches. Which often happens to me in Third Person games. So I put ODST at the top of my Gamefly Q because a friend has it and he's dying for me to play it with him. But I didn't think I was going to get it because it's new and popular. So I put a bunch of games in after that but before Gears 2. They send it to me anyway. I'm like "Fine, whatever. I'll play it anyway." The game doesn't even work. The disc is unreadable. So after sending back Gears waiting for it to get to them, then them sending me Gears 2 and waiting for it to get to me I now have to send Gears 2 back to them and wait then they send me another Gears 2 and wait for it to get back to me. This is what I pay $20 a month for.
