Brand new fridge extremely noisy

I purchased a new Defy fridge last month. When switching the fridge on for the first time it made the worst vibrating noise from the compressor. I logged a service call with Defy. The Defy technician came to my house and laughed at me saying that Defy fridges are "cheap" products that all make this noise. For the record, I have two other Defy fridges that are super silent. I have been loyal to the brand and most of my household appliances are Defy. I have been unsuccessful in escalating this issue to either Makro or Defy. Latest communication I received from Defy indicates that the technician closed the call after "adjusting the feet! This is unacceptable as this fridge is extremely noisy, exceeding normal noise levels. To date, I have had no issues with Defy. Now I am receiving no service and am stuck with a faulty product.
