Quikr Rto — no response with regard to transfer of ownership for car

Address:

c 504 gopalan celestial green apartments old madras road bangalore, Bangalore, Karnataka, 560093

I had got in touch with quikr for their rto transfer of ownership of car services. They charged me close to 3000 rupees and its now more than 3 months.
None of my phone calls are being answered and if at all they answer they just write a mail saying delay is from the rto side.
I have been continuously trying to follow up from my side and have lost complete hope on them.
Request you to help me.
