Samsung Refrigerator Warning

I purchased a Samsung Refrigerator RF266AASH on 11/10/2007 from Lowes. It completely stopped cooling on the evening of 2/13/2008. I notified Lowes and Samsung on 2/14/2008. I was told I had to go through Samsung Customer Service under warranty. They sent a repair person on 2/19/2008 and he diagnosed faulty computer. He ordered the part which did not come in until 2/26/2008. The repairman installed the part and said the fans were working and I should not open it or store any food in it for 24 hours. Well 3 hrs later I checked and the fans were not working and the temp was 69 degrees in fridge and freezer. This morning, 2/27/2008 the fridge is 70 degrees and the freezer is 74 degrees. I called Samsung and they were not helpful and rude. They said all they could do was send the repairman back. This is a new refrigerator that I paid 1700.00 for and I have been inconvenienced for 2 weeks. I have had to eat my meals out which has become quite an expense and I fear I am looking forward to another week without a refrigerator. This is unacceptable. I am requesting a refund so I can purchase a reliable brand. I urge every consumer to beware of Samsung products as the customer service is horrific and the quality is unacceptable.
