Faulty bike

I purchased this pulsar 200 ns in the month of February 2015 and after 1 month it started showing problem in it……so i thought that it was my mistake but after meeting my friend they told me that you should go n talk to the service center peoples and my pulsar 200 NS it’s my first bike and i am not satisfied with it…..so kindly check and please do revert in my mail ID that i have mentioned above…..please do the needful……
