Address:

Patna

HI
I had registered at IGDTUW for recruitment post for the post of
Assistant Registrar - Paid rs 1000/-
Assistant controller of examination paid rs 1000/-
Total amount 2000/- has been deducted from my account, but have not received any payment receipt nor any confirmation on the payment instead it showed "CM 90004- Duplicate Record" . Even the section on payment in
my application shows "N.A".
Kindly Provide me with a solution or return my money.
