Hello, I have a question regarding damage done to my car as a result of a raised bolt in a car park. The low concrete beam generally held to the ground by these bolts had one raised, resulting in the lower bumper of my car to be almost completely detached from my car. When parking, the raised bolt was not noticed, nor was there any contact with it. Upon reversing, the bolt pulled the majority of the screws out of the bumper and barely held on. I am just wondering if this could be treated in a similar way to damage done by potholes and sinkholes, and how I would go about claiming this. It occurred at a bakery so I'm not sure if they are responsible for the condition of the car park, or the local council. Thank you in advance.
