Can an insurance company simply stop communicating with you after it has informed you that they have totalled your property?

In September, I was stopped at a stop light. The truck behind me stopped about 30 feet behind. The driver reached for his cell phone, removed his foot from the brake and when his foot applied the gas, the truck collided with my attached 8 /12 x 18 foot trailer. The trailer was totaled on December 18. I have tried to contact the insurance company and they have not responded. The accident occurred in Virginia. I now live in Kentucky. I have recently paid the taxes in Virginia and have paid the first ticket for it being parked on the street in Kentucky. It will cost approximately $100 per month to house the totaled trailer in off street parking.
