Shriram Chits — requesting for noc copy and form 35

Address:

605004

I have a fifteen years old two-wheeler, which is yet to expire so in order to get that updated, i visited the rto office and enquired about the process involed.
They said you should get a noc copy and form 35 from your finance support institution that is sriram chits,
So visited the sriram chit office, where officers gave null important to my request and simply said, that much old bike isn't worth, and that too that much old documents can't be searched.
So both noc and form 35 can't be issued.
At this point i don't know what to do, and where to complaint
Help please.
