Credr — incomplete two wheeler paper received

I have purchased a 2 wheeler from credr, pimple saudagar, pune branch in august 2017. After two months that branch got closed.
From then i have continuously taking follow ups with credr customer care. They give the same answer each time (U will get the duplicate rc book, it will take some time, we are trying to contact the branch people, documents is in process in rto, etc.).
They don't have any idea when documents will be processed and who is owner of the vehicle, etc.
