MDI Applications

Hi.. has anyone filled the MDI app form so far?

I did the most stupid thing - while entering my acad details, I accidentally selected my 'state' as the University/Board instead of CBSE and made the payment! And now it is not allowing me to rectify this error. I can go to the page and change the board but it is not reflecting in the application receipt. Instead, it is asking me to make the payment again. Even if I make the payment and get a new registration number, what guarantee do I have that my application will not be disqualified? Does anyone have any info regarding this? Or does anyone know anyone from MDI on pagalguy with whom I can connect on this and find a solution to the issue? Any contact number/helpdesk/anything!

I'm in desperate need of help.. would be really grateful if you guys could pour in your inputs!!
