SyncUp Tracker firmware

Firmware update keeps failing for me too and the battery doesn't even last long enough without update so it's almost useless. I ended up with 3 devices because the sales person told me they don't cost anything which was not true, and when I tried to cancel the phone numbers attached to the devices, I was told to pay more than $100 for the devices or keep paying the monthly charges for the phone numbers for 3 years minimum to pay off the cost of the devices. This is a rip off. Anyone interested in starting a class action lawsuit?
