Billdesk — Payment deducted but does not reflect on afcat portal

While paying my fees on afcat.cdac.in portal and filling application fees on it billdesk govt requested my upi id while paying through google pay and then Rs 250 is deducted from my account but does not reflect on my afcat application status . I was waiting for 3 days for the mattwer to resolve and raise the dispute on that payment and did n't get my money back.

Please resolve my issue and give my payment back.
Thanks and hope the you can resolve it.
