What can I do if I was wrongfully accused for an accident with two other individuals?

The two other individuals have State Farm and I have country insurance police came to report. Everyone went home. I called my insurance company to make them aware that I was in an accident but it wasn't my fault. They proceeded to tell me that I was not covered by their insurance. They didn't receive an automatic withdrawal. My agent told me to reinstate immediately so I did it the same day and they took out the month, after that regular premium on regular time and still I'm not covered. They got all their money and I'm being accused of State Farm has been at fault when the other two individuals were in a stop lane and wanted to vacate into my lane which was moving simultaneously. They vacated their stop lane into my truck. Both of them have damage on the front fender and I have damage on my truck from the bumper and passenger side down to the back. I feel why should I pay for something that I'm not at fault at and being accused because the other two individuals have State Farm and my insurance company is not backing me up.
