Bests & Worsts Reviews from Amazon

I have had this bike for 9 months. I used it in combination with the Peloton app, which was a great combination. However, the belt has apparently been grinding on something because I have found shreds of black rubber under my bike. I discontinued use after noticing this. Sunny health and fitness will not speak with me about the issue over the phone, only through email. It has been about a month so far that I have not been able to use the bike, because they continue to not answer phone calls and answer my emails 1 minute before their closing time, always asking for more pictures or video. They cannot find the source of the problem and are not helpful with a conclusion. I am fed up with this and very frustrated that my bike has been out of commission for so long. It worked well for the purposes until I noticed this- although the resistance did also make an awful squealing sound after a while.
