Appliance Repair Guys Mislead by repair technician and ripped off $ 446.45 CAD Oshawa Ontario

My refrigerator stopped working and we contacted Appliance Repair Guys who sent a representative to our house on Wednesday January 8,2014. The technician came and said the starter on the refrigerator was not working and the cost to repair it inclusive of part was $446.35. 

The repair was done and the technician wrote on the receipt 30 day warranty only on starter. The compressor not strong have to change $1200. Five minutes after he left the refrigerator stopped working. 

Upon calling back the company the rude representative told my husband they cannot refund us and they cant do anything as the compressor is not working. 

I am out of options as we are new to this country and did not expect such blatant dishonesty.
