Why the unnecessary rigmarole? Really?

On Saturday, the 22/07/2017, a large appliance (KIC 336 Litre Fridge/Freezer combo) was purchased from Makro Alberton. The item was sold on a mark-down and was purchased from the floor. Matiti Mofekeng was the Sales Assistant. A few hours after powering the fridge on, the motor become intermittently rowdy. Please remember that we are talking about a brand new appliance here, only in operation for mere hours. The motor is not noisy all of the time but only occasionally, for brief periods. My concern is that this is only the beginning and I fear that this problem will become increasingly worse over time. I no longer trust the KIC brand, for obviously reasons, and I would like this item replaced immediately, please, with a different brand. My confidence in KIC has been tarnished since a band new KIC refrigerator became rowdy only moments after switching it on. Why do you insist on inconveniencing me further by contending to set out a technician to my premises. I DO NOT WANT THE KIC ITEM. You are being unreasonable when you suggest that a technician must attend to the problem and then I need to inform that technician that I want the item replaced with a different brand. Where is the sense in that? Why may I not return the faulty item to your store for a replacement. You will make all our lives so much easier.
