[Resolved]  Cars24 Services — Sold car in still on my name even after 15 months

My appointment is [protected] with cars24.
I sold my car up 16 al 3579 on 28th may 2019 and noc from noida rto is done on 29th aug 2019 but car is still on my name.
I raised many tickets but i used to get same response that i am covered with a policy upto 10 lacs.
I have no other option than going to legal proceedings against this as this unprofessional behaviour is harasment to me. Why a customer is responsible for the cars which is sold 15 months back?
Kindly help and suggest further course of action.
