Dear candidate,

The criteria says the participation Fee will be refunded after deducting the processing fee of Rs 1000, if no seat is allotted to the candidate.
There will be no refund if the candidate is allotted a seat in the Special Round
You can apply for refund if not reported to the allotted institute.
You can seek refund of seat acceptance fee through the online portal of JoSAA.
contact the people at the official site and little patience. you MAY get your refund by first week of august as per previous year trends
Good luck.
