Unsatisfied customer.

For the past few months my vehicle has been insured with deal direct. December 26 2020 I was involved in a car accident and now they refuse to pay out. I have no missed premiums or anything. An assessor was sent to assess the accident scene and vehicle.

The computer box was removed and taken somewhere for diagnostics. Now they say the car speed was over the limit at the time. How does this affect payout??? I am paying to be insured. I want this matter sorted out immediately or I will consult higher authorities.
