Ownership of vehicle has not changed.

Myself Karthik and I had taken a loan in 2013 from FAMILY CREDIT INDIA LIMITED (taken over by L&T FINANCE LTD) and i wasn't able to repay the loan of about 3 months (not continuously). Last 6 month of loan was left to completion and i wasn't able to pay for 3 months. I had given the vehicle to my friend before the day it was acquired by them. A person came to my friend's home and took the vehicle without any seizing letter or any kind. I spoke to them about it but they were saying that but they said that they have sold the vehicle it to other without intimating me as they had intimated me through the letter which i got a month later from the date of letter to the date of posting of letter (I argued with them about this also). Now i requested about a NOC or any kind of letter claiming that " In future i have no regards with the vehicle in future". But they keep on saying that they don't give any kind of letters instead they will gave to others who owned my vehicle. Then i requested them to change the Ownership of the Vehicle and they got agreed and said it will be done as soon as possible. Now it almost 2 years the ownership remains the same on me. I has visited them for almost 5 times regarding this issue and mailed to the company also. I had visited recently to the company on 14th August 2017 at L&T Finance Office at Begumpet, Hyderabad, Telangana and they were not able to talk to me regarding this. My QUESTION is there is any kind of legal provision to obtain the vehicle back by filing a complaint on it to nearby PS (because it is on my name) and should i leave it to the company and wait for future happenings. I was worried if the vehicle has some cases they will reflect it on me in future or in near. Can you please suggest with this. You can mail me about this to [deleted]
