Consumer Redressal

I have purchased Yamaha Ray by last december 2012 and after one month I have found that my vehicle\'s entire body color is fading out and launched complaint. They have replaced my some parts of my scooters body part and asked my to pay labor charges. I have paid and again within 15 days I have found that same issue and this time my vehicle is rusting and main back wheel excel support screw also rusted. Head light switch was automatically dead and signal light also dead, scooter storage is flooding with rain water. After long follow up they have again asked me to show vehicle to service center and this time again nothing happened. They have painted outside screws and body in front of me and even body as well. All fiber parts they have polished again and handed over me scooter. Again same nothing happened and I am keeps following up with them. They are doing cheating with me every time. I am frustrated with them and I want to launch complaint now. Please help me.
