All India Institute Of Medical Science [AIIMS] — website showing fee payment not done

I was filling my aiims form, in the step of making fee payment i paid using debit card, but when i reentered the dashboard it showed that it is incomplete... And because of this i am not able to select the city plz plz help.. Or else the because of late submission it may give another city... Which will cause me trouble... This is happening for the first time with me.. So i request you to resolve the problem as soon as you can i wil be really thankful to you
