Cars24 Services — Non payment of holdback amount at time of party peshi .

I sold my car to cars 24, and i was told that they will hold 10000 rs and it wold be released at the time of party peshi. Now the are harrasing me to be present at the RTO without even fixing a date, and they say that holdback amount can only be released after 7-10 days after party peshi. I am not comfortable with this, as they should transfer the holdback amount immidiatly at the time of party peshi.

A representative called me and explicitly told me that no matter if i come for party peshi they are somehow going to transfer the R.C. Without party peshi .
And today the message below was send to me : Hi LEENA W/O MR BHUSHAN,
We are constrained to forfeit the held back amount of Rs. 10, 000 and withdraw our assistance for RC transfer of your Ecosport, UK04s5294 due to non-compliance of RTO mandated Party Peshi . This surely is not acceptable.
I request you to please look into the matter and take strict actions againt the ill policy of company.
