Unhappy Discovery Insure Client

I have been having problems that my rewards are not being awarded, trips are not shown and no response from Discovery regarding my complaints. They say that after 100km you get rewarded, well Discovery has missed a few of my rewards. I have also asked to have the tracker unit checked, as I am often penalised for harsh accelerations, when it is not the case. I am not happy with the so called reward system that often does not work and that changes all the time. Unhappy client.
