Pagadi room issue

Hi, I have bought a room in chawl which is pagdi type with proper sales deed to my owner. Now the landlord is demanding transfer charges 33% of what I paid to my owner. Also he is rejecting to accept rent stating I am not his tenant. The landlord had transferred this room to my owner in past but my owner sell this room to me without the transfer. I bought the room in 15lac and 33% of which comes to 5.25lac which is way high and I don't have capacity to pay even 50k. How I can proceed in this case since my owner is already took his money and gone. I am no where in picture if he send notice since it will come in my ex owner's name. How I can legally attend this case to save my room and money. The landlord is saying that he will send notice to evict me from my room which we bought availing loan from my relatives friends. Is it legal to demand 33% or any amount towards the transfer document ? Please advise since he has given 1 -2 week time.
