Ok, my 360 is being a ***** and I'm trying to take it back. The guy has seen the error happen, but still insists it's the disk, even though I've explained to him that it's happened on 3 discs (2 GoW : 1 CoD 3).
So, I need advice on what to say to him to change his mind that I should get my money back. Please keep it useful, no advice like 'Tell him to shove it up his ass'. I need clever advice, that will make him give me my money back. Thanks alot.
