National Board Of Examination — Fmge application form payment failure

Hello,
When i was applying for fmge june 2023 form, at last page i was waiting for the request from nbe to do payment from google pay .
While i was on the google pay to do payment and at the same time application form payment timing was finished.
I made payment of 7080 Rupees using that nbe link and my application form shown payment failure .
It was systemic failure i understand it, but my payment was done 3 days ago and i contacted nbe call center, i have done mail enough to show them what went wrong. I raised query in fmge helpdesk and my days are going and i am not able to fill up new form because that amount is not small and they have no proper answer regarding..
Now what can i do to get my payment refund asap. It is very much urgent . My application form last date is 20th june 2023 . Please try to resolve by tomorrow 🙏
