I filled a cat2017 form and paid rs1810. After filling the form i noticed my nationality was filled as albanian. I called the customer care support of iim at[protected] and they told me that after filling form and submitting fee we can't change the details. And server will automatically reject the form. I asked for my refund so they told they can't refund the money.
I suppose my nationality is albanian then why it demanded my aadhaar number. I will attach the screenshots. And due to shortage of time i've to fill a new form but please help me to get my money back, because if someone is rejecting my form then the money should also be refunded.
