Canadian Choice

On September 7th and 8th 2023, Canadian Choice Windows and Doors came to do my Artic Insulation and windows and were fully paid before I will get Government interest free loan.
On November I started experiencing mouldlike looks on my ceiling which has never been prior to the Artic insulation. I sent an email to the company with pictures for an urgent attention considering the health of my kids and my wife.
Canadian Choice Windows and Doors almost trivialize the call for urgent attention until I had to be though. Fast forward, this company has been posting me and would not be responsive to the complaint. They eventually sent in a technician who told us the Artic was not properly done and that urgent fix is required and they apologized to us for the inconvenience tgat the vents were all blocked and no vent for air to go out. But surprisingly, when Canadian Choice Windows responded to us, they hinged on the fact that the problem was caused by excessive humidity and advised we buy a dehumidifier and the problem will be fixed. We did get a dehumidifier and it's getting worse still. I have been going back and forth with this company, spoken to some of their managers like Ryan, Mike all incharge of Insulation department in the company . Called consumer care and teams meeting will be scheduled with me and management and they would not show up.
I have tendered a complaint to BBB and they promised to take care of the issue and no one has ever called me on this.
Currently, I am considering a legal action with my lawyer and I have exhausted all options at thus point.
Funny enough, I still have not received my Government interest free loan and this same company Forwarded the wrong payment receipt to my underwriter and the loans Department advised I get the right invoice otherwise a lesser amount will be approved fir my loan. Its been a very bad experience with Canadian Choice Windows and Doors.
