Citibank — citibank forcefully closing my a/c without proper justification

Address:

562125

My name is Samim. Last week I received a email from Citibank saying my A/c will be close within a month, this is not a new account I'm using this account since 2012, there was no such proper justification reason why.

I called to Bank C/care; it was really surprise for me the cause agent said.
I made a IMPS for Rs. 14000, to my father and that transaction their backend team had some doubt and they wanted to know about the details. I given all details to them and the agent said bank will not inform me further steps, I need to call bank and ask for status, my query number: [protected] dated 23-May-2018.

This account was my salary account and based on that I took home loan ECS deduct from this Citi bank a/c every month. If they close my account suddenly I have to run to my loan bank to change banking ECS information which may take little time.

My question is why backend team had not contacted me for a details of a small account that's also a saving account during 1.1Year. My details are very much updated with bank account including my Aadhar, instead of that why they directly send me a account closure letter.

They suppose to update information on 25-May, but today when I called they start making excuses and asking to wait for another 4-5days.
