It looks like that
Some body is going to steal your identity through annonymous calls from bank etc.
open a fraudelent account by your identity and doing illegal transactions. It is a growing business in India. Private banks hardly take care of KYC( Know your customer) norms. Tough Demat account opening procedures, PAN requirement etc. , identity stealing is the new way of crime in India. BEWARE OF ANY CALL FROM BANK/TELE MARKETING OFFICE ASKING YOUR ADDRESS, MOTHERS NAME ETC. As per norm if you receive any call from any call center of any bank, phone banking service, the guy identifies himself first and you have every right to ask any question to him and you may or may not reveal your own information.
only way out is to change your bank.
