Waidler

I had only driven 600m on a road that I have driven on for the last 10 years , its a public road , tried to avoid an oncomin car and lost control , only to hit a tree . According to the so called specialists , some dodgy company called Waidler , they claim that I was doing 143km according to the data they collected from my car . who is this company ? Do they have proper credentials ? They only "collected " this data after 2 months while my car was parked at some storage. My claim has been rejected based on this report from this Waidler , these people cannot go unchallenged , they are messing with peoples wellbeing . My car is written off and I must still carry on paying for a car thats not there due to their untested methods .
