Hyundai Motor India — referral coupon

Address:

Horamavu, 560043

This is regarding one of my referral coupon which i am supposed to get 6 months back. I bought a car from lakshmi hyundai banglore in the month of jan'19 and after few days i referred one of my friend who purchased a car in the month of april. At the time of buying the sales guy promised me i will receive a coupon which i can use for my future service. After couple of days i went to check if the coupon has been generated and they confirmed the sales guy did not punch the coupon hence they will do it now (Pasha). I think pasha is the manager of that showroom. He promised me within a week i will receive the coupon. But till date i have not received anything. They do not pick my calls and even blocked my numbers. I have also raised couple of complaints through customer care but no help. My recent request id is 1-[protected]. This is really sad to see such behaviors towards your customers. I have also pinged in face book but as usual no response.
Please advise asap.
