Cars24 Services — RC transfer pending for my car sold in Oct'22

I've sold my Hyundai Creta car UP92 BP9951 to Cars24 in October 2022. New owner purchased it thru Cars24 channel partner and using the car for more than a year but till today i.e. 22nd Feb 2024 the ownership has not been transferred to the new owner.
Both o[censored]s continually following up with Cars24 still the matter pending.
It's creating mental harassment and a torture kind of experience for me as well the new owner.
