How can i report an issue to the FTC or FCC re: the Dangerous SyncUp Trackers

Recently we were "sold" three SyncUP trackers. The battery lasted 5 days, so I went to return them. T-Mobile sent a UPS return form with LARGE RED letras - do not put this product on a passenger airplane!!!

I, of course, had one in each of my two checked bags on a recent trip! After all, isn't one of the major reasons for having a tracker to find your lost luggage.  The packaging even has a nice picture of the tracker affixed to a bag!!!!!

I really want to thank T-Mobile for putting myself, my family and all of the other passengers on my recent flight in DANGER!!!!

Does any one know how I can report this to the correct governmental agency?
