National Tire & Battery [NTB]

I left my truck in National Tire and Battery. When I got it back, I haven’t noticed that the side foot rail was damaged. I drove it only home and back to work and noticed this damage. I returned to National Tire and Battery, but the store manager said that it was impossible that it was broken in the store. I said that I was sure that it has happened in the store. They don’t want to check or repair it.
