Were were rearended, hit and run, was going to repair truck under our collision claim **-******* until other driver (also insured with Progressive) turned themselves in and took responsibility for accident. Their policy **********. Our claim adjuster is never in the office, will not return calls, said he cannot give us the name of the other insured. He said he would call back after paperwork was done that repairs will go on the at fault party. He never called back, truck is in shop for repair and need to know the paperwork was done so at fault party pays bill and we don't have to pay out the deductible. We need a rental to get to work but can't get in touch with adjuster. Totally frustrated with the way this claim is being handled.
