Hyundai Motor India — regarding registration number and number plate!!!

Address:

New Delhi, Delhi

Serious concerns about libra hyundai (C-180, naraina industrial area, phase-i, new delhi-110028 (India). I bought a hyundai grand i10 from libra hyundai on 17th october 2018 and ever since am made to think that it was a mistake to choose them:
Variant - grand i10 sportz 1.2
It’s over one month now and i still have not received my number plate, registration number. There has been no satisfactory reply or update on this issue. I am not sure why they have still not applied for my registration and if they did so, why are they unable to provide me a copy of rto receipt. No one seems to be caring for customers and always playing in loops about the replies. Its been such an awful experience so far and i am not sure how to get this resolved.
