Dollar Rent A Car

I rented from them in February 2023. I parked in a parking garage and there was column to the left rear of the car. I forgot about it and when I backed out I looked left and right and then at the backup camera as it was a garage and not a busy street. The column was perfectly in my blind spot and I turned too quickly and scraped and dented the door. The repair bill was sent to my insurance who found dollar failed to provide evidence they cost that much. My insurance company kept in constant contact with me and has requested documentation several times but dollar will not return their calls. When you rent from them you sign something that says in the event of damages, you the driver will have to seek payment from the insurance, the driver is responsible for all amounts due. The only communication I have received from dollar is a statement, a threat to send to collections and harassing calls saying they will sue if I don’t pay. The claim is still under review with my insurance today and I am in collections with dollar for them not fulfilling their obligations. This has tanked my credit and caused significant stress. I’m learning they do this all the time. Do not rent from them.
