Poor Service and even worse customer care

I bought a brand new fridge less than a month ago. A week ago I noticed it stopped getting cold. So naturally with the item being brand new I went to the store 1st thing the next morning. They were helpful enough until it came to actually replacing the unit. They want to charge me R350 to collect the broken fridge and to deliver the replacement. This is absolutely ridiculous. They couldn't be bothered to assist me or even offer to do it for free after selling me a faulty unit. Not so much as a sorry for all the food that's gone to waste either. Will never recommend a Hi-Fi Corporation to anybody nor spend a cent at 1 ever again. How can I be expected to pay a delivery and collection fee for an item that I never broke in the 1st place??? Utterly disgusting and exploitation to the fullest. Plus I have to give 48hour notice before I intend on collecting my refund from the store.
