Worst Service from Defy Appliances

I notified Defy on the 20 January about my fridge that is under warranty and stopped working. After a technician came out 2 weeks ago, I was promised 3 times this week that the repairs would be done. I took off from work 3 times this week waiting for someone to come do the repairs but no body pitched up. I recieved no phone call or any apology or reschedule. I had to call again only to be told that no one can come out this week. This has caused a direct impact on my job and perishable food that has gone off. This service is unexceptable!
