Query: Terrible customer service

Fan went bad 2 days after got tv. Have waited over 8 days and still haven't gotten a confirmed date for a repair call. Samsung appears ambivalent about poor service and insists that we must have set repaired and not replaced.Will deal directly with amazon.com on Monday, and expect them to replace the set.Samsung's poor service and ambivalence either due to arrogance or incompetence. Buyer beware!
