Discovery Insure is not working

I have joined Discovery insure from June 2019 and since that time I struggle to get my information right in the system. The sensor failure and also no driving information is available in my page due to wired message "You have no score because you do not have a device installed. Find out more." But the sensor has been installed by TWT and confirmed by Discovery Insure. I tried to call Discovery to sort out the issue but when I called and asked them to fix i, they giving me nonsense answers like it will be fixed after a month and you have to wait for a month then it will be activated, etc. Really, tired and wants to cancel the plan.
