I just received my new rw200 rower last week and was finally able to get a friend to help me assemble it. It went together easily until I tried to pull the handle to test the row bar. It was difficult to pull and made an awful grinding/screeching noise and now will no pull at all. I have called your service line at least 5 times with no answer and have been on hold for over an hour two times with no answer. What is the problem?? I need someone to please call me back ASAP.
