Income Tax Department — no sign of refund despite over 30 days

I receiced conormation of my IT returns and refund for AY2019-20 almost 30 days back. My refund has been confirmed and my bank account has been already validated in my efiling. Still there's no sign of refund. What is worst is that the CPC helpdesk is just fooling around.

They ask me to pre-validate my bank account, which is alreday done. They pass call from one department to another without resolution. They close the helpdesk call with fake resolution. See the screenshot.
I asked for refund status and they ask me to validate the account which is alreday done.
SBI helpdesk has no information. NSDL TIN website has no information.
It's loud and clear that IT department of india is all time cheater. They are not commited to pay the refund.
What's wrong if I evade incometax going forward? The PM of this country goes for round trip of the world from the money I pay to him thru incometax and when it comes to get my dues, they just fool around.
I made a big mistake by choosing mody government again. %^$%@^$%#^$%
