Best Buy review: Warranty

My wife and I purchased a washer/dryer pair about 6 months ago, along with a treadmill. We also purchased the warranty on all items. Last month, the treadmill stopped turning on. We have contacted Best Buy multiple times and are told our issue is not covered, even though nobody has even bothered to come take a look at it. Extremely disappointed, to say the least. If this goes unresolved, will never shop there again, and am even considering legal action.
