Why are Indian private banks so unnecessarily difficult for NRIs?

Seriously, I’m losing my mind trying to handle basic compliance from abroad.

Tried updating a simple registered email and overseas phone number on my NRO account. One customer care executive tells me to do it via the net banking portal, which keeps throwing random server errors. Another tells me I need to physically courier hard copies of my passport and documents to my home branch in India.

When I actually did that, they rejected it saying my signature doesn't match the one they have on record from 8 years ago.

It genuinely feels like the banking system is actively punishing you for living outside India. Has anyone found a single bank that has decent online customer support for overseas compliance, or are we all just stuck dealing with this 90s-style paperwork loop?
