Replacement takes forever and defy isn't communicating

I logged a call on November 28, technician came and repaired the refridgirator, the following morning it was hot in the cooler again. When I told him he said it is to be replaced. Replacement in the making 57 days later, I still don't have a refrigerator. I spoke with Logan Kroutz and she in December. I sent her couple of emails which are not answered to date. I call the office she is nowhere to be found for the past 2 weeks.
