Collision shop for a repaint? Just don't do it.

Thanks 1968 Formulas340- Im worried now. I took my car to a insurance shop(I assume) but I did not know. The Guy told me he would love to do my car. I took it to him and now it is getting pushed aside. To make matters worse some bare metal areas that were sanded are rusting on a body that was rust free. I'm disappointed. I might go get it tomorrow
