Cardekho — RC Transfer to new ownwer

I sold my car to Cardekho in January 2023. They claimed to do RC transfer within 180 days.

It has been more than 10 m months since I sold the vehicle to them

However unfortunately they didn't transfer RC till date.The car is still under my name. Since I am not in India I am worried about if anything happens it will affect me. I called and mailed them several times but not getting any response regarding this. I need RC transfer of my vehicle as soon as possible.

I had been in continuous contact with them, and getting the same reply, as it is in the process.
