Customer service?????

My freezer i won in Jan 2012 packed up in November 2015. Your service department sent out a technician to assist but the problem wasn't fixed and carried over to the new year. I received a call from your service team who said its past the 3 year warranty and then turned around to say it only had a one year warranty as it was a comp prize. Now i have a unit that was worked on by one of your people and still broken. Your service department refuse to help and now i have to pay for repairs out of my own pocket.
