Poor Customer Service and *********** Technician

I'm very frustrated towards Defy. Technician came on Wednesday 21/12 to fix the double door fridge which freezer side is not freezing. He declared that he has fixed the fridge but found out it still not working. I called technician directly since I had a number same day to come and check which he promised he will the following day. Thursday I called this *********** technician and he told me that he forgot about me and he will see during the day. I did call afternoon which he did not pick up. I called service Centre and new Ref was given ***. Made several attempt with call Centre today which they told me that fridge will be fixed on the 28th. Where is the fairness in this... Where I'm suppose to store meat that already bought? Meat is already rotten because my neighborhood their fridges are full. I'm requesting urgent intervention from Defy management and quick fix in this. Thanks
