Dear Raja Sir,
Kindly clarify whether Deficiency memo was issued on 19-2-2021 or SCN was issued?
Assuming that SCN was on 19-2-2021 and followed by an order on 19-3-2021,
Your ideal course of action is to file an appeal within statutory time limit of 3 + 1 months. Now since this time limit falls during COVID-19 period (15-3-2020 to 28-02-2022) under Supreme Court Suo Moto Order dtd 10-1-2022 - 2022 (1) TMI 385 - SC ORDER, you had time up to 90 days from 01-3-2022 i.e. 30-05-2022.
I am unable to understand from the facts as to how natural justice is violated as 1 month was given to assessee in SCN, which was not replied by him.
In my personal view, when a refund claim has been adjudicated, new claim for the same period and same issue cannot be made as the appropriate route is to file appeal against the rejection order. ( to my knowledge, the portal also doesnt permit a refund application under the same head for same period).
The only remedy I find in your case is that if you have justifiable reason for not filing appeal till now, you can challenge the order rejecting the refund before the Hon'ble High Court. Though chances of getting relief seems to be very meek, you can surely make an attempt.
