Bajaj Auto — no proper service and cheating

Address:

Chennai, Tamil Nadu, 600130

I left my bike for service in Manickam motors siruseri chennai for service. While leaving, I told the service person that my low beam light is not working. Immediately he told that bulb fuse would have been gone. I told them ok please change. At the time of delivery they told that we changed the bulb and while im doing a test drive it was still not working. While asking to the service person he is saying that it is because of heat, we need to fix a two way switch so that only it will work. But what actually happened is the wire which is leading to low beam was in a loose contact. I have been cheated that bulb fuse gone and I didnt get the low beam issue fixed yet. Is there a way to clear this up ? I can't even imagine how bajaj is not noticing these kind of thefts.
