Netstar is the worst

In 2020 I joined Netstar. A tracking device was installed in my car in August 2020 and I received a fitment certificate. I have been paying my monthly premiums since then. Fast forward January 2024 I found out when I called Netstar wanting to update them that I’ll be using my car for business use, they told me they don’t have any contract of me for the vehicle I was giving them. I was soo confused because infront of me I had the fitment certificate with my name and my vehicle details. They told me that when they punch my ID they find a blue Hyundai with GP registration number. I told them I don’t know that car and I have never owned that car. Apparently the details of my car was linked to some Lindokuhle Hlatshwayo that I don’t even know. I told them I don’t know that guy and how come he owns my car now and when did that happen because I have a fitment certificate. They told me they will call back but never did. I kept calling them and sending emails but they ignored me. From January until May 2024 they were avoiding me yet deducting my monthly premiums yet I was literally driving an uncovered vehicle. I’ve been calling and emailing from Jan to May without getting any help. All of them would promise me they will investigate and get back to me with an explanation of what happened and will reimburse me if necessary which they never did. I called them again beginning of this month and they finally sent someone to come and remove the old device (which I’ve been throwing my money on it for almost 4 years) and replaced it with a new one. Still no explaination of what happened. Still no explaination of how and when they will reimburse me for all the premiums I’ve been paying all these years. No calls no emails from them. Nobody is telling me what would have happened if I was kidnapped or my car ****** because I wouldn’t be traceable. This is really worrying because they had put my life in danger. What’s even more confusing now is that after installing this new device beginning of the month, they have just deducted an amount way more than the package I signed up for. A lot is going on at Netstar and it is worrying to say the least. All I want from them is an explaination and my money.
