Progressive Insurance Progressive Insurance Lied to Us. False mayfield village, Ohio

My car was hit on Nov 22 while it was parked. I notified the authorities and Progressive Insurance. On Nov 29  I received a call from a progressive adjuster advising that my car was a "total loss" and that I would receive a "pay off" amount. I was further advised that once I received a payoff amt that I would have 72 hrs before Progressive would no longer pay for the rental car. About two hours later I received a call from someone in Progressive Insurance Investigations. I was told that my accident was under investigation. I was asked if I wanted  to change my story about my car being parked during accident. I was further insulted when the investigator suggested that my husband was driving drunk during accident and that if my husband just admitted to being drunk that Progressive would still cover the cost of the vehicle. I tried unsuccesfullly for 4 days to reach the investigator. On dec 4 the investigator finally returned my calls only to CHANGE what I was told previously in that now since  my claim is under investigation that I was now responsible for the payment of my rental car and that my "investigation" could take weeks or months. I asked for his supervisor,  I was told that he was on "vacation" and that no one else could help me. I've done everything that was asked of me. Quite frankly I'm being treated very unfairly. Neither me nor my husband consume alcoholic bevarages and we do not appreciate being accused of such.
