Disappointing Netstar Service. So horrible

I have taken a Netstar early warning option on 29 Jan 2024. To this day the device they installed in my car is not working. They replaced the first device but the new device is also not working. It gives wrong location and they keep sending alarm messages based on wrong information. When I login to their App is not pulling my records. So I can't my cars. Now when I call they say they are working on it and promise to return my call but they never. We called in yesterday to cancel the contract but the agent helping us said only her manager can assist so we don't incur early cancelation fee. He said she will call yesterday still but she never called. Netstar Early Warning option is a waste of money and time. I'm moving on and will reverse the debit orders. I am currently paying for nothing. I am so so disappointed.
