Central Seat Allocation Board [Csab] — Refund of csab 2020 fee

This is Rishika Bajaj. For further reference my jee main application number is[protected].
It's been like a month since the csab 2020 round 2 finished. And I wasn't alloted any seat according to my rank and preferences. Still there is no notification of money which I am supposed to receive as a refund. I have sent numerous mails to the e-mail provided on the official. Also the complaint number provided on the official website says please check the number you've dialed.
Expecting an update about the same. It's been way too long and there's still no response from your side. If the same continues I might have to some serious action. I expect a response from your end before I'm done being polite.
Look into the matter as soon as possible.
