Strong Smell Inside Refrigerator

The unit is a RF268AB purchased at Lowes in March 2010, serial number 43FB4GBSB00360D

We have tried baking soda, vinegar, washing with a dishwashing detergent and crumpled newspaper as the technician from A&E suggested. Nothing works. The smell is as strong as ever with an alcohol smell which has permeated all the food inside. If I could afford to do so, I would roll it out to the street and buy something American made.
