Samsung — Replace compressor of refrigerator - Lost bill but still under warranty

Hi,

I purchased a Samsung Refrigerator in October 2013, which is still under 10-year warranty. I raised a service request no. [protected] as the compressor is not working. However, the technician said he would need the original bill to work on the request.

I am unable to find my original bill, and would request you to help with the details I have:
