Tneb — voltage fluctuation in pallikaranai

I am a resident of paari street, vgp shanthi nagar, pallikaranai. For months together, we have very bad power fluctuation and voltage drops here. When my electrician checked in the afternoon he said it was 160 volts only. Our ac is not working at that voltage. Hence he advised to put a double boost stabilizer, which he said will work even upto 140 volts (Costs around rs.4000). I did that. Even after that during nights, the double boost doesn't work after 8.30 or 9.00 pm (It seems voltage drops even below 140 volts!). I am afraid i will loose my good equipment like fridge, ac, heater, tv etc. Even fans do not gain speed and make eerie noises at night, and we are sweating. This is the issue faced by all the residents of vgp shanti nagar, pallikaranai. Pregnant women and kids are suffering every night. Request tneb to take necessary steps immediately to stop voltage fluctuations.
