Tamil Nadu Electricity Board [TNEB] — No power supply for 24 hours in maduvinkarai (Raj bhavan, guindy)

Address:

Chennai, Tamil Nadu, 600032

There is no power supply for manthope 2 nd street, maduvinkarai, guindy for 24 hours time.
Still we are facing the issue, we use to call frequently TNEB Section Rajbhavan [protected], but the numbr is out of service. no one is pickup the call while trying for TNEB Section Rajbhavan AE :[protected].
the worst part is we tried for TNEB Section Guindy :[protected], they simply told not their scope of support as well no any other contact numbers.

so how i proceed further?
Is it the way the govt response for people who paying tax and bills on time?
there is no rain fall on last 2 days, what is the fault makes the power supply cut for more than 24 hours? why the team can't fix it till now.
are they aware of this issue?

Whom to i escalate further???
