Mr D motorcycle driver collision

Mr D motorcycle driver has smashed into my car on the 20th December 2024. I have sent many emails to them to claim for damages. No rep from the company has responded to any Emails. When u call the support, they just say it's been escalated and nobody replies to emails or return my calls. I am not the only person that has encountered a problem with Mr D drivers. They are foreigners who are very reckless on the roads, and Mr D is avoiding the Claim.
