Bad and unsatisfactory customer service

My car has been with this panel beater since the 7th of December 2021. My insurance approved my claim late in January 2022. The panel beater is still unable to finish fixing my car and they are continuing to change their estimated dates of completion. I'm expected to understand their issues yet they continue to ignore my challenges. I have been without a car for 3 going to 4 months now because of their incompetency. I continue to experience financial inconvenience each and every day because of them. I do not advice other insurance companies to recommend them to their clients. Private clients must, at all costs, avoid using these people.
