Hero Motocorp — hero duet

I had purchased a hero duet in april 2017 from your dealer shubham motors jaipur the scooter chassis no. Mbljf16esggc19120engine no. Jf33aaggc25554. It skid twice on road, i got injuries at both the times-fractures. The service centre shubham automobiles is not providing proper services. When i visited for service the staff refused to attend either on ground of days or kms. Today they said we will do 6th service only because all other coupons are invalid. This is a breach of service. Kindly look into the matter.
