Honda Cars India Ltd. — Offer given on Dealing was invalidated on claiming

Address:

Ahmedabad, Gujarat, 380007

Last year I purchased Honda Amaze car from Landmark Honda, Ahmedabad.
I was given buddy loyalty of Rs. 3000.
I purchased the car through an agent, who offered me this scheme of buddy loyalty, which I activated.
I was told I could use this buddy loyalty at ANYTIME and that I could use this for my paid service or changing any car part or anything from Honda.
But now that my first paid service is due, nobody is responding on the mention of buddy loyalty. Also when I contacted the agent, he said it is valid only for 6 months.
It feels like I am CHEATED.
I expect you you look over this problem.
Thank you.
