Royal Enfield — common key set change

Address:

New Delhi, Delhi, 110020

On 28th of october 2017 i got my desertstorm serviced from south delhi motors delhi. Yesterday while riding i saw that the right hand side cabinet of air filter was open and the lock was not there. Is this my fault or the service center's fault?? They changed the air filter and other things on my bikes 5th paid service amd charged me more than 7000 rs. When i went to the service center they syltarted arguing stating that this was not a fault of theirs and it has to do something with my way of riding. On top of that they said that i might be lying. Apart fron this lock set there was another nut that was missing which was the one for the leg gaurd. Another thing was that i changed break pads on 28th but the brakes were not working this was confirmed by one of their representatives. Still instead of apologizing they didn't had any regrets about the pathetic services they are providing. Because of this silly mistakes i had to buy a new common key set and they charged 1650 rs for that. I want that money refunded to me and strict actions taken against them.
