Tamil Nadu Electricity Board [TNEB] — Poor response from EB staff at Mamallapuram office

Dear Sir,
Greetings!
This is to bring to your kind notice that, the way your staff at EB office at Mamallapuram is horrible and irresponsible.
Today afternoon I called the above office number since there is no power in my street for quite long time. Your staff picked my call and asking me to contact my area wireman to understand the issue office don't have any idea about why there is no power.
Is the process your office is following everywhere?
He mentioned his name as Kamallakannan.
Would be grateful if you could take necessary action on him. Please give proper training to attend customers queries and to update with proper information for same.
Thanks for your understanding and support.
Awaiting your response.
