Unprofessional and poor in handling my accident case

In November 2019, I was involved in an accident with a car from Volvo, the guy was wrong and he admitted that he went through a red robot, we did the accident report and he said he was going to take the paperwork to the office for processing, this went on for weeks without any feedback being provided to me, after a month, I contacted Volvo to find out the progress and they told me that their fleet management company (Eqstra) was handling my issues, they gave me a case number and when I called the company, they asked for a whole lot of documentation which I provided, remember there is already and accident report that could have told them what happened instead of them asking me for the paperwork anywhere after that they sent my details to another company (Palm & Hollander Attorneys) which the company is close for holiday and they will only process my application in January. After so much inconvenience I still don’t have a car and I am still waiting. With Volvo being a big company, I didn't expect so much unprofessionalism. This has impacted me and my family so much and I don’t think I will ever use or buy anything from Volvo anytime soon.
