Tenway in Toronto

This company told me that it will give me free air conditioning when I purchase a furnace. After paying for 2 years plus they were still charging me so I put a stop through my account and they started to call me asking me to pay 17,000 because it is what I owe them. After 1 paying 167.00 for 2 years plus. How can I pay almost twenty thousand dollars for just a furnace. When I refused they took my name to Credit Bureau to spoil my credit. Very very bad company

I went to a show home in mcconachie area and the staff was very friendly and great . She explained some things about company and about their homes . She was wondering and know her staff.
