Since you requested cashout today only, I suggest you to wait for at least 48 hrs. more. During weekends their payment merchants might be unavailable or this might be a problem form your bank's end. It is too early to postulate anything.
And one more thing, please use crypto, it is easier to track and almost instant, no need to rely upon third party to confirm anything.
My fiat contact suggest to wait 72 hours before escalating to them. So OP,
adroidanky, please mention me [it'll bring your topic to my attention, suppose this thread fell off my mind] if it's not resolved by 19th November.
And regarding the use of crypto, if I understand the situation in India correctly, their govt. put a heavy tax for crypto transaction, in hope to suppress crypto, so INR fiat is much preferred by Indian players.
