[Resolved]  RTO India — non transfer of vehicle

Sir, i had sold tata 1109 to an individual in oct 2019,. He hasn't transferred this vehicle to his name. I had provided form 29/30, bank noc, valid insurance and all other required documents. But still it's above 3 months, the person is telling lie that he has transferred the vehicle. I check statues frequently on govt site.
