Billdesk — amount deducted but transaction unsuccessful

I tried paying the registration fees for cat 2020 using billdesk upi qr code. The amount got deducted from my account and the transaction status is being displayed as 'purchase confirmed' on google pay app. But as per the official cat 2020 portal the transaction was unsuccessful. I saw a lot of complaints regarding the same issue here. So i hope that it's gonna get resolved quickly keeping in mind the fast approaching deadline.
