Jawaharlal Nehru Technological University Hyderabad [Jntuh] — no call is answered ever

Address:	Hyderabad, Telangana, 500085
Website:	jntuh.ac.in

I tried calling on all the numbers provided by jntu-h but none care to respond it once. Could this be looked into please. Because many ex-students like me may keep calling from different states to get some information or do some enquiry and if nobody at jntu-h cares to answer any of the official numbers given then we would simply need to come to university from far places just to enquire small doubts related to our credentials etc.
It is just a humble request to the higher authorities to look into this on priority and fix it.
Thanks in advance!
