Unhappy customet in Mississauga

This is the worst most frustrating company I have ever dealt with. They did our roof but the shingles are falling off. I have been calling them for one month and and they are refusing to respond. I was finally told that Johnathon would be coming today October 9 between 10 and 11 and I still have yet to hear from him despite two phone calls. Save yourself the aggravation and their so called 10 year warranty on labour. Use another company Use someone else! They do not stand by the “quality “ of their work.
