Query: Bike is ok worst customer care.. Be Careful

This is a good bike for the price. But one of gear in my bike aft system broke in half after 3 days of buying. It's fine but when I called customer care they asked me to sent the onvoice and I sent it. After three days when I called them they said it got shipped. And after a week when I called stating that I didn't yet recieve it, They said they don't have the spare for it and it will take 4 to six months to get the part. You know what tell them to shove the whole bicycle in their ***. I have bought a new gear system.
