First, the man who was contracted to remove my mattress called in advance and asked if I would be able to help him carry it out. When I said I could not, he enlisted his son to help him. They arrived and told me their shoes were clean. I trusted them and let them upstairs to remove the mattress. After they were done, I signed the paperwork saying nothing was damaged (again trusting that their shoes were clean). Shame on me for not looking closer at the carpet before signing, but what I found was grease and dirt marks left from their shoes. When I notified you, your company refused to assist with the cleaning costs because I had already signed the consent release. Lesson learned.
