My sister is an NRI. She called her bank main office to find out the exchange rate from INR to GBP. The local bank manager, who usually handles her account called her that evening asking her if she called them to find out the exchange rate. She did not give her personal account number or any details. All the system had was her phone number.
Is her personal information allowed to be shared like that to the local manger as she was not happy that he found out about her phone call and the conversation she had
