Lowe's problem with warranty Willow Grove PA Nationwide

 WE purchased a $2000 Samsung refrigerator 2 years ago with an extended warranty.  It broke in August The repair people have been out 4 times for repair.  Each time it takes 2-3 weeks for parts to come in and then the refrigerator breaks again in a few days.  WE have essentially been living out of a cooler since August except for a few days.  We have to buy ice every night and cannot keep a lot off food in the house.  Children need to buy lunch at school, $50 every 2 weeks, because lunch meat does not keep well in cooler.  They say we can rent a refrigerator, but I don't have the money to rent it nor do I want to use a refrigerator that others have used.  They say to get a replacement it must woRk for 30 days 3 times, then break, but it has been repaired 3 x since August.   They cannot tell me when part will be in to repair it.  Maybe Monday, But Thanksgiving is Thursday.  I complained to customer service that I needed a refrigerator for Thanksgiving and she told me once her oven was broken on Thanksgiving.  This is why I purchased a warranty!  I also do not have room for a rental, but was told by supervisor of customer service that is not his problem.  I  have been working on this and would like to face the holidays with a working refrigerator.  My refrigerator was my wedding present and it should not be so much trouble to get it fixed.  I was responsible in purchasing a warranty, but no one is helping.  Really in this day of overnight shipping, does it really have to take weeks to get a part?  thank You if you can help. I own an Samsung refrigerator, phone and washer
