Nightmare insurance

My car was involved in an accident last year July. And my mother asked is my insurance company not suppose to take my car for a full inspection before approving my claim and they did not do that and I dismissed it trusting they know what they are doing. Pineapple approved my car to go be fixed and the garage that was fixing it did not do a thorough job on my car and it kept making funny noises and doing funny things. When I took my car to the dealership they discovered that my insurance did not take care of of the problems that needed to be taken care of properly and I sent them an email January 16 2024 and they said they will respond and up until now nothing. I have been sending emails and no one is responding and yet they take my money. I haven’t been able to use this car because I’m afraid I may cause further damage and it has been inconveniencing me. Can someone sort my car out or someone please advice me on how I can take this matter further because this is *****ulent for me.
