Yes Bank — bad service

I had requested a yes bank nri account. I am based in europe and had very high hopes on getting a good bank. They were really helpful while opening the account but immediately the relationship manager is changed. They keep changing the relationship managers and did not provide good service. We waited and kept requesting them to take actions but no response.
Despite requesting to close my account from past 3 weeks there is no result. Will not recommend this bank to anyone.
