Tamil Nadu Electricity Board [TNEB] — Power cut more than 5 hrs at night

I'm praveen from sembilivaram, sothuperumbedu EB office. When 9.30 they cut the power then after 11.30 only the power came and then after 1 hour they again cut the power till now the power not came. If i call to sothuperumbedu EB office always the connection in busy. Most of the time they do this kind of service only provided. Time is 3.00 AM what they do we don't know here all the godown and company have power but we don't how it possible both the power are transfer in same transformer from EB office but they only have.
