Bluestar refrigerator beware!

Sent many Complaints to bluestar About our recently purchased refrigerator making a high-pitched noise. Per Bluestar, this is normal operating conditions for this refrigerator and they will not do anything about it. This was an extremely expensive refrigerator and blue star is not standing behind their product. I would think twice again about purchasing products from bluestar. This refrigerator has been nothing but problems. I have all their emails. Extremely disappointing.
