I have a nordictrack elliptical and have hearing a clanking sound so called them. And without sending out a tech they tried to troubleshoot over the phone. They sent me a huge heavy part then sent a tech out after days of trying to contact them. Tech came, realized the part sent is not the right one. He ordered another part for me, received it, tech took a while to come again. Part couldn't fit, this continued for 3 more times. And I had to call and get mad. And after 3 calls finally this lady customer service understood and sent me more parts. Arrived and guess what, wrong again!!! This has been going on since july and it is now november.
