Tamil Nadu Electricity Board [TNEB] — No power for last 12 hours and still no response

There is no power at my place Perumbakkam Annai Indira Street near Pasumpon Nagar from 6.30 am and there is no response from the eb office. There is power all around the area expect this street. There is less water available since majority people use the bore well which needs power, many have online classes and work from home. There is no idea till when the power cut will last at least to get prepared. There is no rain still no response from them. A solution required for the issue so kindly help solve it
Thanks in advance
