After a query with Netstar, I was informed that the battery on my tracking device was flat, and I had not been notified. But I was still paying the monthly subscription. I was then told that I had to take out another 3-year contract to replace the device. I sent several emails to query how long exactly the device was inoperable, why I was being debited and why I was not being reimbursed. No feedback received so I eventually had to cancel, which also took 2 months, with no response from Netstar. Really pathetic service. I would rate 0 starts if I could. Account ***6
