Geeksquad is a national chain effort with hit and miss quality and certainly a mix of people. I applaud the idea, but would never call them. Read the contract you will be entering with them about the repair. Be aware that some will disagree at replacing a CDROM to fix a machine but with labor rates being what they are, hardware is often cheaper than fiddling to see if you can coax it to work again.

Best of luck,
