I'm sorry! You will not be able to add or invest more money to an on-going (existing) Term / Fixed Deposit. You can, of course, continue to save by investing in a new term / Fixed Deposit with a fresh value date.
You can book New Fixed Deposit by following few simple steps:
1. On Mobile Banking
1) Go to Banking -> Fixed/Recurring Deposits
2) Open Fixed Deposit
2. On Net Banking
1) Go to Investment -> Deposits
2) Open A Fixed / Recurring Deposit
