Svp after a 11 months

Hello everyone,

I have not bought svp when i bought the car last year march 31st.

Dealer told me that i can get it later on also.

Its time for service now and i am thinking of buying it as its cost efficient in Bangalore location but now dealers are telling me that i can get 2 years of svp only not 4 years.

Is it a tactic? Have anyone faced such scenario?
