Nmail tneb

It seems like you're trying to communicate something, but the text is a bit jumbled. Could you please rephrase or provide more context so I can better understand what you're trying to say?

From what I can gather, it looks like you might be trying to say "TNEB mail" or "Tamil Nadu Electricity Board mail"? If that's the case, I'd be happy to help you with any questions or concerns you might have about your electricity bill or any other TNEB-related matters.
