Dissapointing service and Faulty Appliances

I recently purchased a Defy fridge from the GAME store in gateway. I had only put on the Fridge for three days about 2 weeks ago because I hadn't moved into my flat till then. I put in my groceries and left the flat. I came back 2 days later to find out that the Fridge had not cooled a single bit and over R1300.00 worth of groceries had gone off. I called the GAME store and was advised that a gentleman would call me up within a week to come and look at the fridge. He did come and look at the fridge and advised that he will call me back. Its now been over one and a half weeks and I still haven't received a call and I'm unable to use a fridge that's literally brand new. I think from an aftermarket customer services experience - this was utterly disappointing also to loose all that money I did in regards to the fruit meat and veg and no one from GAME cares. The Fridge is still under warranty! Almost everything I've purchased for my flat as I've newly moved in was from GAME - Including my 55inch ultra HD tv, cutlery, utensils, cleaning agents, frames as well as food. I assure you - I will no longer be supporting this franchise and I will also be advising friends and family to not support this store if this is the way they treat people. Someone needs to call me and sort this **** out including my expenses ASAP!
