Unhappy client

My vehicle was damaged during the floods in April 2022 and deemed not drivable by King Price, as the drivers door would not open amongst other damages. The vehicle was towed from my property and i was provided with a courtesy car. It was kept at an assessment yard and assessed more than 2 weeks later. Thereafter it was taken to a workshop to begin authorized repairs. My trip to hell and back begins a few weeks later when the courtesy vehicle was taken as the loan time expired. During this time there was very poor communication between the insurance company, the allocated workshop and myself, so much so that almost 3 months later my vehicle was still at the panel shop. I had to forcefully remove my vehicle by this time as i was being sent from pillar to post with claims being rejected due to wear and tear and some brought down to maintenance. They claim to be doing the hood lining as a courtesy for what im not sure. Even that job was not done correctly and left the vehicle with more damages as the sunroof no longer opened. The excess still needed to be paid for a rejected claim. After all these months my vehicle was given to me in the same not drivable condition as no repairs were carried out and there are now more damages and accessories missing or ******. This has been my insurance for many years and i have never had any previous hassles, this is definitely by far the worst way of treating a client and handling a claim. I have logged a formal complaint with King Price but to no surprise theres no response.
