Jawaharlal Nehru Technological University Hyderabad [Jntuh] — Refund of money which I applied for OD

Address:

Kukatpally

On 4-5-2021, I applied for OD.

At first I tried to pay through billdesk and it showed 'failed' and 'the session has expired'.

After that again I tried several times (due to server problem) through Internet banking and with the gap of few minutes two times 3500 rupees were debited from my account.

So what is the status of my application ??
And totally they took 7000 rupees from my account instead of 3500 rupees and the didn't returned to my account.

Please do the needful and please return back the extra money which was cancelled.

Thank you!!
