Poor Quality Fridge

I am very disappointed with Defy - in July last year I purchased a brand new Defy DAC675 C450 Nature Light fridge from Hirsch's Centurion. It is just over a year old and it has been giving constant issues. In June this year it stopped getting cold and Defy sent a tech to do a warranty repair - the tech regassed the fridge and it started getting cold again, although it was now running extremely loudly. Fast forward 4 months to October and it stopped getting cold again - Defy then again sent a tech who took the fridge apart and then said there was a blockage and he needed to come back the next day. He replaced the whole compressor and did some work on the fridge, and now it is getting cold again. However 2 days after the tech had been here the fridge's internal fan has started making a loud grinding noise which goes on and keeps us awake. Opening the fridge door stops the fan and the noise, but it continues shortly after the door is closed again.

I am very disappointed with this fridge and it certainly does not meet the standard of quality I have become accustomed to with Defy appliances. I have lost the contents of my fridge twice now due to these faults and the noise it now makes is unacceptable. Defy has had 2 opportunities to repair the fridge and so far the problems have not stopped and I feel the unit should be replaced.
