Tamil Nadu Electricity Board [TNEB] — improper power supply

I made a same complaint on july 6, but it was good for a week and the old low voltage issue started again. I've registered a complaint in person but no one came to check. It's been a week since i complained. The ac trips off and then turns on. This happens through out the night and occurs for a moment for every 10 minutes. The ac and the stabiliser are working good. The problem is with the power supply. Kindly do the needful
