Tamil Nadu Electricity Board [TNEB] — Metre wire cut in the night

Address:

Mangadu, Chennai

I live in mangadu, chennai
And on 27/8/21 around 2.00am in the night, I noticed that there was a power cut. I waited for a while as this is very common in my area but it did not return. A few minutes later I noticed that the street light was on as it was shining very bright through my window. So I was worried that the supply is not there only for my house. I went down to check the main board of my house and found that the wire connecting my metre box alone has been cut and my metre box is completely off and the rest of the houses in my appartment are up and running.
I have lodged a complained to managdu eb office since then. A person name Martin was the one who spoke with me and spoke in a very rude mannaer and impolitely.
He refused to give me assistance on this situation and more over out right refused to attend my complain tonight and said it will only be dealt in the morning.
I have no clue as to what to do now. I'm unable to sleep, disturbed and distressed.
Mangadu eb office is one of the worst if not "the worst" in responding to any of my pleads. They lack empathy and no one there is willing to do a honest day's work. Especially Martin and Dhayalan.
