WATCH: Son Confronts Salesman Pressuring Elderly Mum Into Buying New Doors She Didn't Need
A man has gone viral after recording himself confronting a 'cowboy builder' he alleges ripped off his mum.
Dominic MacMahon's mum is 81 and has dementia. He explains she was cold-called by a window company who then sent out the guy in the video, Mark Gibson.
Dominic claims his mum complained of a loose door handle, but that Mark talked her into spending £6,000 for two doors that she didn't need.
Talking to the camera, Dominic explains the situation before he enters the house: "She should have been given a new door handle for £50, not two doors for £6,000. Let's see what Mr Gibson has to say."
"I don't prey on old people," Mark says. Before Dominic drags him off to go and look at his shoddy work.
"My mother is very vulnerable, you knew she was vulnerable," Dominic replies, somehow managing to keep his temper.
"How much money will you make for ruining my mother's life?" he asks, before forcing Mark to explain why he told his mum that her door was unsafe when it wasn't.
Since uploaded the clip last week, it has been viewed 4.5 million times and has had over 100,000 shares.
