Trident Hyundai, Bangalore — sale of second hand car

Address:

560033

Hi,

My cousin sold her car to trident. The representative took the rc and asked her to sign the docs. Once signed he is now telling that the money will be transferred only once vehicle is delivered. He is also threatening to give the vehicle. Is there a service like this? Is this authorised? The representative name is vedamurthy. Kindly investigate and do the needful.
