Netstar: absence does not make the heart grow fonder

I recently found out by accident that my newly upgraded tracker had not been working for nearly a year. After trying to make it my fault (!), I was told someone would get back to me. No one did so I called to cancel my contact. I was told I can't do that without paying penalties. I said that I would not be paying since my teacher unit had not been working for a year. Again I was told someone would get back to me. 6 days later in still waiting. Netstar really sucks! I AM cancelling my contact. I'm glad I no longer have to rely on them to recover my car or be there in case of an emergency because they're just absent!
