Car 24 — payment not received

I had sold my volkswagon polo to car24, paschim vihar, delhi branch on 09th march 2019 for rs. 270000.

They give option me for instant payment which i choose but they deposited rs.1000 in my account in 2 hrs. And now its 5th day i didn't received any amount from them thay are only making fake promise every day and saying that we are already transffered but it is not transfered because of server down but when i discuss the metter with my own bank it say that in last one month there is not any report of server down. Then i realize that the car24 is making me fool.

Car24 is a complete fraud company
