Kemore 12 Cup Coffeemaker

I received a coffee maker in December for Christmas. As of June 7th it is no longer working. I look in the owners manual and it states that "it is under warranty for two years from the date of purchase, return it to any Sears store or other Kenmore outlet in the United States." I took it to the Sears store from which it was purchased and the manger said he can't take it back even though I have a receipt because Kenmore is not their company. I show him the written warranty that says "take it to any Sears store." The owners manual also states that they are a Sears company. He still will not take it back saying that they are now owned by Kmart and the rules have changed. Which I tell him Kmart bought Sears two years ago how does this affect a purchase I made 6 months ago. The best he could do was to give me a 1800 number to Sears. I called the number and they said that I had to call Kenmore and they never heard of Kenmore. I go back to the manager and tell him that Sears has never heard of Kenmore as we are surrounded by Kenmore appliances and Kenmore is written in big letters on the wall behind us. So I went home and dialed 1888-Kenmore and they gave me the runaround and patched me through to Sears. I informed Sears that a company called Kenmore is using their name in it's owners manual and promising to take back any defective appliance for two years after the date of purchase. They gave me another number to call. I don't think they are going to honor there written warranty.
