Auto Owners Insurance review: Slow/nonservice

On 12/1/2021 I got into an auto accident. I phoned my insurance company Liberty Mutual because that is what I thought you were supposed to do. After Liberty contacted me I was informed if I went through Liberty because if I wasn't at fault, I would have to pay a 500 dollar deductible and would be unable to have them pay for a rental because it wasn't in my policy. Liberty had already the truck to Copart in Midway. Auto owners the driver at fault's insurance company rented me a vehical and sent a check for repairs but were unable to get the truck because Liberty had not transferred to Auto owners. Her insurance agent and myself made several calls to get the transfer to Auto owners which was said to have been completed several times. On the 4th of March it was transferred. I have been trying to contact Auto owners leaving messages etc. I can not him to call me back or get truck moved to repair shop.
