My bike was working fine but due to brake problem I had to take the bike to the service center.Everything about my bike was perfect, from the sound box to the battery. Then when I came to know that the sound box of my bike had suddenly got damaged, I suspected that it was this. Happened only by the service fraudster. That was perfectly fine sound box after 4 days it sounds burst out..And when I told the company that this is so and how can my sound box get damaged just four days after giving it for your service, they said? Anything is possible.
