Disgusting service

In February 2018 I purchased a Defy upright fridge from House & Home. Was over happy with product until early December 2018 when the fridge started leaking. Water was collecting under crisper and seeping out the door. Also water collects on each shelf then drops onto the food in the fridge damaging the food items. Since December have reported the issue 3 times to House & Home. Each time a technician comes out and cleans the drainage. Works for a few days. Three weeks ago we noticed water at back of fridge. Reported the again. Same Technician comes out again this time to put in a heating thermostat .Not why cos if the fridge was meant to have this it would been built into the fridge when it was initially manufactured. I refused to allow the thermostat to be added and requested a new fridge or a full refund. This call was 2 weeks ago. The technician assured me within 2 days we will have feedback as he will forward a report to his manager. It's now 2 weeks later and not a word from Defy. All is silent. Disgusted with pathetic service. 3 months after reporting the problem with the fridge and still no resolve.
