IT demands of earlier years which were already paid, adjusted again from current refund by Dept.

Income Tax Demands of AY 2020-21 & AY 2021-22 were already paid when demanded.

Now same demand again deducted by Dept from refund of AY 2022-23.

Submitted grievance but got automated reply saying that demands of previous years are deducted, without much explanation, and they closed the query by showing it as resolved.

How to solve this matter and get the amount back from IT Dept, as this was already paid?

Please guide.
