I have filled ITR and it got processed.But the refund issued is failed due to PAN not linked with the bank account. So I have submitted refund reissue request with another bank account details which is pre-validated in efilling portal.This request also got rejected. How to get my refund and how to check the reason for rejection.Please help on this.
