I just used the 1-800-883-8102 number on the OLPC wiki page to cancel my OLPC "Give One, Get One order and ask for a full refund I had the "pleasure of speaking to a surly gentleman who gave me no confidence that the refund is going to happen I'm guessing he's on minimum wage, is following a script, has no understanding of anything beyond what's on that script and has had a lot of calls like mine today
