Bad service

Western Insurance is giving me a problem to claim the 30 % of the accident damages which was caused by their insured which was also part of the accident.I have been sending Emails and even calling but no one is giving me a feedback or response since the 09th of January and the other party settled their 70% of the damages caused by their insured client since they were jointly liable for the accident that happened on the 29th of June 2025.
