I am a religious follower of my mail-in rebates and NOTHING sneaks by me due to my diligent tracking. I submitted a $50 rebate a couple months ago when I picked up the Sidekick 3 and accidentally put my phone number on the form not knowing that I needed to put the number for the phone I was upgrading to get the rebate. I resubmitted the form with the right number and just received another form back saying my rebate was unable to be processed. I swear these companies do everything in their power to not give you the rebate after sucking you in with a good deal. This rebate is from T-Mobile so there is no way I am giving in this easy and they really need to think about who they are trying to mess with before picking their fights.
