Don't rely on Defy

I just purchased a Defy frost free fridge about 2 weeks ago. Within 3 days had 2 swop it because it was consistently beeping. Fridge no 2 arrives then there are noticeable dents on the inside top of the fridge. Obviously I'm not going to keep it because the fridge in the shop doesn't have those dents. We swop the fridge again. Fridge no 3 my oh my it was making a big noise first i tried to ignore thought it will settle after a few days. Then on the 4th morning i wake up to find everything frozen in the fridge compartment yet this been a frost free fridge. From my milk to my food to even mayonnaise frozen. I went to the shop and asked for a full refund. I got it. Will never purchase another Defy appliance again because they are definetly NOT RELIABLE!!!! Worst experience ever.
