Knight Plumbing, Heating and Air Conditioning

On Aug, Knight Plumbing replaced our water tank. Upon removing the old tank their employee dropped it and damaged our door threshold cap. We have contacted them numerous times. The first time they said it was only a $ part and we could get it at. After spending hours at hardware stores we found that the only place to purchase the part was on Amazon for a cost of $ plus delivery. We have tried several times by phone and email to contact Knight Plumbing but we are only being ignored. We would like to have them come and replace the broken door threshold and we are seniors and unable to do this ourselves. This damage was clearly caused by their careless employee.
