NordicTrack review: Customer service

Worst service ever! I have been fighting with Nordictrack since July over my commercial 2450. It took weeks for the technician to come out . It's just over a year so I had to pay $160 but parts were covered. They found glass in the motor . The tech assured me it came this way because he could tell the motor cover has never been opened. Took pictures and ordered parts so I thought. Three weeks went by and nothing … so after finally being able to connect with three different people the parts were never ordered. I was told it was my job to order the parts. Why would it be my responsibility to order parts? Waited another week for parts to come and another three weeks for tech to come out . Tread still squeaked so loud , he needed to order more parts . He ASSURED me he would order the parts. Another week went by and the parts were not ordered . I call today and they said my warranty was canceled due to negligence ? How can this be ? I’m currently waiting to hear back from the supervisor who cancelled my warranty . There is zero reason my warranty should be cancelled. I’m beyond frustrated and so upset I’m paying for a machine that we can’t use. The customer service is basically unreachable and when you do you are transferred several times to rude, scripted , helpless agents.
