First of all, savings accounts are meant to be used for savings purposes only. If you do lots of transactions on your savings account, the bank may freeze your account citing transaction patterns. I suggest everyone open an individual current account if you make lots of transactions.
Second thing, the bank's RCU (Risk Containment Unit) can take the decision, and generally, RBI won't interfere in this kind of matter, so escalating such cases won't help in most cases.
I agree nowadays bank account freeze is very common, but honestly, the majority of people make lots of credit and debit transactions using a savings account, or do lots of UPI transactions using a savings account.
What you can do to prevent such things:
- If your purpose is to make lots of transactions, open an individual current account. You don't need a business to open a current account, an individual can also open a current account. Or at least get a higher variant savings account.
- Avoid using digital or zero balance accounts for high-value transactions.
- Always declare your financial profile correctly. Sometimes people quote lower income while opening a bank account fearing tax-related issues, but such mistakes can create issues like account freeze, as you'll be doing a lot more transactions than your declared income.
- Update your profile (on the bank's file) from time to time.
If you still face any account freeze-related issue, you should work with your bank to identify the issue and try to resolve it. If your bank is not willing to unfreeze your account, close it and move to another bank or open a new account. And obviously, file a complaint against the bank if your local branch or their employees don't help you resolve the issue.
