I purchased the Proform treadmill from Costco.com. I then purchased the 4 year extended warranty service from Proform.com. 2 years into the warranty, my belt is broken. I contacted Profrom, they assigned the warranty to Icon Fitness, Icon Fitness sent the parts for the belt. But assigned the actually repair job to Altitude Fitness Repair in Colorado. But it's been a month, no one would call and schedule an appointment to come and service the treadmill. I sent emails, texts and web live chats. Everyone is kicking the ball around and no one would respond to the repair. Basically, I paid the money for the warranty plan and will not receive any after-sale service. Costco is willing to take the treadmill back. But I just wish ProForm, Icon Fitness and Altitude Fitness Repair in Colorado would step up and honor their obligation.
