Plumber On Demand

I needed a waterline connected to a new refrigerators and called plumber on demand. The plumber installed the line but it started leaking an hour after he left. I called them back and they said the plumber would come the next day and fix the problem for free. The next morning the plumber called and said he'd been instructed to charge me a call out fee. I called head office 4 times and each time they said a supervisor would call me (and never did). No one ever called me back and no one came out to fix the problem. In the end I replaced everything myself with a bit of YouTube help and at a cost of around $10. Extremely disappointed that plumber on demand wouldn't even call me back and I couldn't even get to speak with a manager or supervisor, and did such a poor job to begin with (which cost me $186 for 10 mins work).
