Cars24 Services — Unprofessional behaviour and

Extremely poor service and professionalism by cars24. They assigned an ameture agent to handle the deal duhita sood. No clarity in required paperwork. Gave part information through a span of 1 week after making the offer which was accepted. After 1 week the car was not picked up by making several excuses. They connected me to a supervisor as well who promised to complete the process next day. After 1 week they revert with a watsapp that deal cannot be carried out. No courtesy to call back or even pick up my multiple phone calls. Poor is an understatement.
Due to this i had take a huge loss as i already had a buyer at a good price whom i lost since cars24 promised to buy within 24hrs which never happened
