Indira Gandhi National Open University — no response from the ignou study centre sathaye college mumbai

1. I have registered with ignou for ma economics. Study centre is sathaye college, mumbai (1603). I had been writing to the centre for non-receipt of study material, enquiries related to assignments, guidance for studies. But there had been no response since sep 2017.
2. I wrote to regional centre, mumbai (Rc49). But they also didn't respond.
3. How can a student study when the institute itself is not providing any support to the students? The institute, not even once has interacted with the students (No reply received for last 6 months, ridiculous!!)
3. Its very unfortunate that with such a enormous responsibility of educating the youth of the country in hand, they are not doing justice to their task properly.
