Maybe You can get them to stop the junk mail and so-called free stuff...they have been sending me the same literature for years and I just save the crappy note pad and misc stuff and throw the sign up away!Since Your Son is under age maybe You can cancel it all together?
Tell Your Son never to OK or sign anything any more unless he talks it over with You first!Sad part is Your going to recieve all kinds of Spam and Junk mail for a long time now!
