Defy - worst service ever continues

I shared my bad experience with Defy last week and they sent their senior technician who replaced the compressor. The fridge now makes a howling wind like sound every time the compressor goes on.

This is a brand new fridge that I purchased under the assumption that it’s new and from a reputable brand which I have known for years has had to have a new compressor installed just after months of purchase. I now worry that it will not even make it past a year at this rate. My house is full of all defy appliances but after this experience I cannot see myself replacing them with defy. I never had such problems with my old defy fridge and with this “new one” it’s one problem being fixed with another on what is supposed to be brand new. Do defy now sell second hand appliances at major outlets?

I maintain…still the worst service ever. A fridge should last at least 10 years.

They will probably escalate the matter and send another technician (for the fourth time). But can we really resolve the issue at hand, which is that I was sold a defective/faulty fridge...I need a permanent solution to this matter.
