Openserve may have damaged my car

Openserve is digging up the pavement and driveway at our house even though we never asked them to. They have placed a huge pile of sand and rubble in the drive way. To get into the yard I had to drive over this and I heard my car s****ing underneath. They did nothing to move the rubble. I had to get into the yard. If my car is damaged, Openserve will pay for the repairs. I need to go out in a short while and they are still doing nothing about the rubble blocking the driveway. In fact, one of your staff is just sitting ontop of it.
