Bad NRI service

I am frustrated with the NRI service. Now the bank has been decentralized and the service is almost a nightmare. The interesting fact is no one knows any system properly and even the bank managers are not ready to do anything more beyond their daily routine. It is hilarious to see the staff not knowing which swift code is closed. Anyways, they do not have enough time to answer queries from other banks through MT195. All in all, it was a horrible experience I had with the arrogant rude people, and even after 90 days, my problem has not been solved where other banks do it within 2–3 working days.
