Sears South Coast Plaza Costa Mesa, Ca Purchased new washer/dryer making loud noise and Sears will not fix or replace Costa Mesa California

In july,2018 purchased new Kenmore stacked washer dryer combination, total cost $1,413.10. A short time after turning on the washer, it makes a loud continuing noise with a burning smell. I called Sears and made appointment for their Appliance Service to look at the unit but he did not show up. I made second appointment for Sears Service to look at the unit. The Repairman showed up but said that he had a busy schedule and could not wait the short time for the washer to start making noise after turning it on. The Repairman left without ever looking at the unit to determine or fix the problem. The Sears Service people at the store don't care or want to deal with the problem as it was announced that the store will be closing.
