Careful with 3rd party claims from dotsure s client's

Good day everyone I would just like to warn you last year I was involved in a motor vehicle accident with a client who belongs to dotsure I've tried to claim from them to pay for my damages which was caused by their client and they refuse to pay for my damages because according to them their client didn't cause the accident I've sent footages whereas their client admitted he will pay for my damages I've sent them witnesses statements even their client's blood results showed he was under the influence of alcohol 0.20 and still dotsure refuse to pay for my damages which was caused by their client's negligence They also refused to send out a expert to the scene to determine who the cause of the accident was Very unprofessional so people don't ever try to fight a 3rd party claim with dotsure
