Immobilizer not working and NO Help for 7 days

My car immobilizer alarm goes off every time I drive the car, the immobilizer remote is not working. I called Netstar 3 times and sent email but still no assistance. It's 7 days now I cannot drive the car and Netstar is doing nothing about it. Month-end they will be debiting my account for a service not rendered. The call center agents don't even know what to do with my query, it's like I'm speaking french and don't know who is supposed to fix this issue. I think getting another tracker company to remove this one and install a new one is my best bet now. Because the people who have installed this one and I'm paying every month are just failing to do what they are contracted to do.
