Benjamin Franklin Plumbing

My mother had her pipes done and had a life time guarantee.. about two years after having they were done the pipes began to leak and flooded their whole bathroom. They needed fixed and she was told the group who did her work wasnt "sanctioned" and they wouldnt do anything to help her. This place is a joke. They were obviously advertising and they were in the phonebook. So how did no one know they were out here doing work under the BFP name...
