Do NOT use Netstar!

Can one to lower than 1 star? This is a truly BAD company. They stopped tracking of my vehicle. When I phoned to have them check I was told tracking was happening and all was well. When I asked where they thought I was it was about 600*km from my actual location. Effectively they cancelled the contract with me by not delivering the service, effectively invalidating my insurance. They promised to fix it but did not meet the mutually agreed deadline. No feedback of course! I am still being charged! I told them in writing to stop the debit order on my account immediately, which they have not done. I stopped it at my bank and now I'm being harassed for payment???? Looking deeper, I see I am by no means the only person this has happened to! My advice for people looking at a tracking device? Steer well clear of Netstar!
