Tamil Nadu Electricity Board [TNEB] — frequent power cut at mid nights

My residence at rangasamy street keelkatalai which comes under moovarasampet eb service. There is frequent power cut at mid nights. Last mid night no power for an hour. This mid night it's been more than one and half hour, no power here. Last week also same problem at mid night. This is so ridiculous, if we call eb office, number is busy, sometimes they say only two at work, they will come and fix it, till that v need to wait and there is service issue coz of overload. Is this causes tolerable at mid night with crying kid, experiencing such a worst eb service. Take necessary action immediately.
