Manav Rachna International University [Mriu] — security deposit not returned

Address:

Faridabad, Haryana

I am passout student of[protected] btech civil batch.
I have succesfully completed my btech from fet department of manav rachna in civil branch in the year 2016.
At that time i have submitted all the noc, forms etc which was required to get degree and security deposit which was submitted while joing the institute 2012.
They forcefully deducted 1000 rs for alumini from the security amount and told that, we wont get your degree if you dont agree to it.
After all that, they were suppose to refund students security deposit in form of cheque or dd.
But till date (After 2 years aprox) there is no information about the refund.
They are enjoying interest on the amount which was submitted 8 years before by the student.
I tried to contact the college for that same, but no one is interested.
No one picks up the call in the accounts department and civil department has no information about the same.
There is no email id provided on there website, so that i could mail it to the higher authority.
