Hyundai Motor India — car rc and number

Address:

Street no.2/5, H.no. 70, Krishna Nagar,Modi Nagar,, Ghaziabad, Uttar Pradesh, 201204

I have purchased i 20 car from modinagar branch during august 2019 but i have not received rc and car number at yet (Dated 6th oct. 2019). As i know take hardly 10-15 days. Hyundai is very popular name in world but i am surprised in this case. I have visited in showrooms numbers of times for the same.
Kindly look into this matter seriously
