CARS24 Services Pvt. Ltd. 4th Floor, Plot Number-65, Landmark House 65 Sector 44, Gurgaon-122002

I have sold hyundai eon dlite+ (Mh03 bh9140) from delhi location through cars 24 dated 03/11/19 against appointment id [protected] to nimisha mal in inr 1.25 lacs on behalf of whom mr. Adrian elliot collected the vehicle & did all the formalities. It was already informed to cars 24 & buyer as well that noc has been issued by mumbai rto for delhi (North zone), delhi (Dl) vide no 2916/e2013 dated 26-sep-2013 but was not registered in delhi, also this information is clearly available on vahan e services and post verification of all documents only cars 24 asked for service charge of inr 3k which was paid. Then later on request from cars 24 i have assisted them to get the bank noc again & confirmation from delhi rto (North zone) that noc is not been used. But now its 7 months +, vehicle is still not transferred to buyer and no updates of the same is been provided by cars 24 till date. Also i'm unknown of the situation if the vehicle is been used for any illegal practices/affairs.
