Filled three ITR 1 at Official ITR portals, two of them on 15/07 and the last one 18/7.
1st ITR - Zero problem - Money received on the Bank even the next business day.
------------------------------
2nd ITR - Despite the green tick on the pre-validated bank once filled Income Tax AI didn't find linkage of the bank's IFSC code to the Account holder pan card, So the Refund amount is not possible to transfer - solution: "need to raise a reissue refund claim" which says the Intimation Email from CPC Bangalore.
The problem is that there is no refund failure according to the Website so generating a refund raise out of question. No such problem in any previous year, always / whenever applicable refund received in this bank account without any problem.
On the other hand, this bank does have the merger though, Immediately visited the branch with a bunch of screenshots on my tablet upon explaining to the branch manager replied - all individual accounts are updated with the New Bank name and IFSC code along with PAN number - The final steps done by (if not done, then blame) RBI.
------------------------------
Now the Major Problem:-
3rd ITR - This one required actual tax payment which is done on 18/07 by generating Tax payer counter foil (under Major Head: Other Than Companies 0021, Minor Head and Self assessment tax 300) and paid through SBI net banking and it is immediately credited to Gandhinagar SBI, Bangalore in the return of 7 Digit BSR Code and 5 Digit Challan Number.....which correctly inserted under Tax Paid Tab -> Add Advance Tax and Self Assessment Tax.
After that successfully validated and E-verify ITR and submitted it.
On 20/07 - there is a Red Intimation mail at the Email arrived, please pay the exact same amount of money that was paid two days ago as the tax credit mismatch for AY 2022 due to not being able to find the Challan Number which generates enough discomfort for the genuine taxpayer mind. On the same day upon Calling Help Line No of CPC Bangalore: 1800 419 0025 and explaining the situation to 3 Individual Persons (all of them are quite surprised) they (the last person) generate the Response To Outstanding Demand which is now out of my knowledge and required a charted accountant to intervene which will going to cost at least 3-5k.
------------------------------
Again this is a pure case of Over Promised and Under Deliverd of E-Governance - This is how 164.5 Core AI failed.
Human processing (tax officer) required a minimum of 60-120 days, not 48 hours during the peak filing season.
