Hi.

According to Official FAQ Published by AACCC:

Security amount will be refunded only after 20 working days from the date of publication of refund details by AACCC in their web-site www.aaccc.gov.in

The security amount will be refunded to the same account from where the security amount was initially deposited by the candidate.

E.g. If the security amount was deposited through Card #1234XXXXXXXX5678, then the refund will go to Card #1234XXXXXXXX5678 only. If the security amount was deposited from account # 123456789012 of State Bank of India ISF Code SBIN0003567 then the refund will go to then the refund will go to # 123456789012 of State Bank of India ISF Code SBIN0003567 only.

Hence the candidate should keep their card/bank account active till refund process is completed.

I hope this helps.

Good Luck
