marques in Toronto

I called them to repair a leaking pipe on a Sunday morning. They told me if they come Sunday it’s $300 if they come Monday it’s $190.00. The hole in the ceiling was open for them to do the work. They cut out an 8 inch piece of pipe and replaced it. They charged me $550.00. Later on that evening their connections began to leak. I asked for money back and they refused. I will be filing a complaint with the Better Business Bureau.
