Yamaha Motor India — Service terms and condition

Address:

Vishwakarma Auto Yamaha Showroom,Shimla-Kangra Rd, Ghurkari, Himachal Pradesh 176001

I went to vishwakarma auto yamaha showroom, kangra for servicing my r15 v2. When servicing they said if any part get damaged then the agency is not liable for that. So question raises here is that, then why should i opt for an authorized agency for servicing if they not held responsible. What kind of service, yamaha kind of big brand promise to provide. It was pathetic to see such kind of terms and condition.
