Hyundai Motor India — i10 grand delivery and service issue

Address:

Sec 34, Gurgaon, Haryana, 122001

Since i've booked this car dealing of sales team has been very disappointing.
I've been told to take delivery in 15 days and when i reached found car as fault,
Repainted new car was handed over to me
Whan after confirming to pick rc i went it was in another branch which blown my mind as the team their is not providing correct information
After 1.5 month i asked for 1st service of my car took appointment 2 days before from last 4 hours i'm waiting for person to come and pick my car

Was supposed to get it around 2 pm thye told me to take it by day end

This is sheer irresponsible behavior of himgiri service centre in gugaon sec 34

I was promised a voucher of 3000 as referral to be given to one person who referred me i'm yet to receive the same from 1.5 months

I'm mentally harassed to such a level that it forced my write it here

I thought of going to consumer court but i beleived in hyundai company would never want customer to be pissed off to such extent

Let me know the recovery thing and get this issue resolved
