Sansui India — sansui split ac service center presence missing

Address:

India, Gautam Buddh Nagar, Uttar Pradesh, 201301

I've bought a sansui split ac 1.5 ton, 9 months back with an assurance that my a. C. Will be serviced on time. To my surprise, the nos provided and the email addresses both doesn't seems to have presence.
I am appalled the post sale service and their commitment, never seen a product which dupe their customers the way they do.
Very poor or no service.
