Josaa — refund not received

I withdrew my seat from college before 7th round. After completing online process, i also followed their whole procedure at rc and got a seat withdrawal letter. Now a month is over and i haven't got my refund of rs. 35000. During fee submission they asked me to pay this fee in a day, then why don't they refund it now. Do they not understand that we need that money for admission to other colleges. Please instruct them to proceed further.
