KIC fridge noise - no consumer rights

On Thursday, 2 April we took late delivery of a KIC fridge from House & Home, Sandown Crossing, Parklands. The delivery person told us to let it stand for 24hrs before switching it on, we did. Upon starting up the fridge it started making very bad swooshing sounds and at some point sounds like it will \take off". We escalated this back immediately (four days post delivery as it was Easter weekend). We then waited for a KIC technician to come out (24 - 48 hours turnaround). The technician proceeded to tell us that the fridge needs 3 weeks - 2 months for the \""gas to settle\"" and left without checking the fridge. Upon further investigation we found this \""settling of gas\"" story to be totally untrue. I then contacted House and Home again to rectify this noisy fridge situation. Alex"
