Sharing confidential details of your Bank Account or your Card with any person can land you in trouble as your details can be misused to withdraw money. So please refrain from giving such information to any unknown person......still better not to share them with anybody for that matter.
Banks or their officials will never call you or send an email/SMS to reactivate your account. Nor will they ask you for sensitive information like Password, Customer ID, Debit/Credit Card details, OTP, etc. Any such Phone call or email/SMS is an attempt to fraudulently withdraw money from your account. Never respond to such Phone call or email/SMS.
