Samsung Air Conditioner

I purchased a Samsung window air conditioner, Model AWO6ECB7XAA, from Lowes on October 23, 2007. I paid extra for an extended protection plan.

Seven months later I called the Samsung number, 1-888-775-6937 to report that it was not emitting cold air.

Their local authorized service dealer, Class Appliance Center, picked it up for repair on May 10, 2008. After keeping it for 7 weeks and three days, it was delivered and installed back into my window on July 2, 2008.

Same problem as before - - - no cold air. The delivery person, took it back to Class Appliance Center for more work.

Why was I not offered a new replacement unit?
