Fc Universal Ltd

I used Appliance repair Aurora they out source to FC Universal LTD. I'm out $904.00 and my fridge doesn't work. I called them to fix the temperature display that hadn't worked for months but the fridge ran great. Now I have a display that works and reads 77 but the fridge doesn't work and they want me to be out more money as they can't come when I'm not working. DO NOT USE APPLIANCE REPAIR AURORA!!!!
