How do you know the people who work at those shops didn't replace your console with a banned console? Because when we submit our console, we will check the serial no. at the back then record it down on the receipt. Then when I am getting back the machine, will check the serial again. Better than no checking at all.... I know this is an old post, but did you check to see if the serial matches the one that is in the settings firmware? The serial number is in in a few places. The outer shell is pointless.
