Delivery not on time!!customer service suck!

I went instore to purchase a Samsung frenchdoor fridge the 29th,First they said they have no stock ,only the demo that is on the floor.i went instore so i could get the fridge quicker.well the guy was very helpfull and said the fridge could come tomorrow (the nextday Saturday)or on 3-5 days.well im still waiting everything is just radio silence.This is not how you treat a paying customer.atleast let me know that delivery is going to take longer or just something.My other fridge gave in now i have to put my stuff in the freezer and run back and forth so the stuff dont freeze.Also if you have a black friday sale why is there no stock instore? Im past the point of frustration.i dont know what you doing but we have a problem!.
