Mahindra Finance — Regarding document of vehicle purchased from auction.

I have purchased a HONDA WRV with registration no. MP06CB0956 from MAHINDRA FINANCE AUCTION and the vehicle was got released on 29/04/2022. Today is 15/08/2022 i. e. 168 days(around 3.5months) and still I haven't received any document to transfer the vehicle to the new owner.

I am attaching the release letter of the vehicle below...
