Cars24 Services — Car RC still not transferred even after 90 days of sell

Address: Bengaluru

Dear sir
I sold my car to cars24 on April 27, 2022, however, even after 90 days the rc is yet to be transferred.

While the cars24 clearly mention that the liability of the vehicle is transferred to them, to the owner, unless the rc is transferred it remains a burden.

I have been following with their call centre as there is no other channel through which can be reached.

However, the response is always cryptic that the complaint has been forwarded to concerned division.

My only reason to go for cars24 was to have a hassle free paper work even though the price quoted by them was very low. However, it has turned out to be a great disappointment.
Kindly help me in resolving this issue.
