BR and CN both are painful for me for this reason. Try to use a credit card, they will try to SMS a phone number I haven't used in my bank for 3 or more years.
Now that OP tells us about IN i'm starting to see a pattern: for a fraud and insurance company, or being realistic, the payment processor middle man who offers those services at a loss, making their client lose a few sales while pushing their customers (you) to instant electronic payments (BR:pix, IN:UPI, CN:IBPS etc) is a much better deal (for the middle man)!
you seem to be older. I used this too. Until 5 or so years ago. Now my bank just says i "don't have to notify them anymore as they don't have this in the system, since it is all automated for my convenience"
but nothing works
Wrong on all accounts. There are orders of magnitude less engine models used in air than cars. Profit margin for airplane companies are higher than cars (though volume is much lower). cars use the same model worldwide and pass certification all at once, planes sell in one country and customers are mostly responsible for 'acclimatization' or whatever they call it in your parts, but it usually is about lights color and placements or some nonsense.
the one thing that made planes be so slow, is that people who own planes have much more voice over legislation than people who own cars. Nothing else. That's why the whole industry used tax payer money to certify one special new gas type that will work on all existing engines (again, possible because much less variety, making it easier technically). You breathed lead for 60 years of legal lethargy just so a few people didn't have to spend a few pennies on their plane maintenance.
