Customers should regularly verify their bank account details, including the account number, account holder's name, and the selected currency for repayment (either United States Dollars or Bhutanese Ngultrum). It is also advisable to ensure that your email address and contact information are up-to-date, as ORO Bank will use these channels to communicate important notifications about the redemption process. Keeping this information current not only facilitates a smooth repayment experience but also helps you stay informed about any updates regarding your investment.
