Aiims Map — Multiple payment not yet refunded

Sir/mam,
I tried applying for INICET 2020. My registration Id is P[protected]. The amount was deducted on my first attempt via SBI Credit card but the web page displayed it as payment failure. I tried on my second attempt now via SBl net banking but it went in vain and the amount was deducted but showed as payment failure.

I waited a day and one of the payments had been accepted and my application was processed. But I did not receive a refund. I emailed aiims regarding the same and got no reply back. I tried contacting the toll-free number and the other two mobile numbers mentioned on their website as well. But Nobody picks up. It has been more than a month since my account was debited, still, I am yet to receive the refund nor any reply from the aiims.
