But aren't obligated to inform this on closing request itself? Atleast you should have received alerts for the same upon giving closure request, that some credit balance is pending, give request for withdrawal/ transfer into your bank account, like SBI did in
@vine case.
They weren't supposed to remain silent about this, that you have credit balance of ₹0.06, kindly give us consent to credit the amount in your account. Upon sucessful credit, we will be able to close the account fully and permanently, till then it will remain cancelled.
They are doing practicing unfair trade practices, that's all.
