Hyundai Motor India — registration certificate didn't receive yet after months of purchase

Address:

Panipat, Haryana, 132140

Sir, i purchased verna sx (O) on 27th jun'19 from sawan hyundai panipat. Till today i have not received original car rc and i am also not able check the status. Whenever i call to dealer to know about rc they either did not pick the phone or after picking the phone call they say that they will call back after 2 minutes after getting information about my rc but they never call. The service is very pathetic and not customer friendly. Still i am worry about my rc when will i get it. Its almost 4 months. Please help and take necessary action if required.
