Unprofessional worst service from miway

I am a 75 year old women I feel miway took an advantage that an elderly. I received the worst service ever from miway I’ve been having them for years as an insurance for my car. My grandson stole the car while I was sleeping then the car was later involved in a car accident. Mind you I didn’t give him the car he stole it so I did not give consent they wrote off the vehicle. They made me wait for whole two months without a car while they were taking monthly premiums and promising me that they’ll approve the claim. Then after the 2 months they rejected my claim as if I gave him the car but he stole I thought insurance is supposed to cover things like this they even told me I’ve been claiming while I was with them was I not supposed to claim worst service ever unprofessional. After rejecting the claim they sent me a new renewal contract of my car with new premiums.
