Car damaged

I took up an car insurence with Dial direct a week ago. They said Netstar technician will come to install tracking device it's part of their insurence requirement.

Technician came and install the tracking device, late on the same my engen had a different sound from the previous one, the follow day I had a oil linkage. Now my engine has oil overywhere and it's dripping down. I got stuck on my way to work.

The same technician came back and saw the problem but he couldn't fix it because the engine is bad.

I dont know why dial direct forced me to take netstar, they broke my car
