Bad Service

I purchased a Defy refrigerator at the end of Jan2016. After receiving a brand new fridge & plugging it in, it began making a weird gassy noise. I called Defy, they sent a tech (Jeremy) to inspect. This happened in the same week of purchase. Tech said new fridge had to be vacuumed & re-gassed. After which I heard nothing. I called Defy again & tech claimed he never inspected the fridge prior to this & proceeded to make arrangements for another inspection. 2nd inspection arrived at same result, vacuum and re-gas which was done on 9Feb2016, I reiterate, on a brand new product. Tech thereafter confirmed noise will stop & they will followup the next day. No followup was received. I followed up with them on 12Feb2016, informed them noise is still there, tech confirmed he will report this to customer service. More than a week passed, I heard nothing. I eventually called customer service *** on 19Feb2016, manager Mark Mitchell said report confirmed all in order. I explained this is a lie, manager said tech will inspect again to which I refused. Still waiting for a call back from manager (25Feb2016). Customer service is apalling. I require a new replacement at no additional cost.
