Tamil Nadu Electricity Board [TNEB] — Voltage is too low

I'm a resident from Ramanathapuram panchayat in Avinashi, Tiruppur. Incoming voltage is so low even mixer and grinder will not start at times and can't use any electronics without a voltage stabilizer. It's the case that's not recent and going on for a while. Providing connections more than Transformers operating capacity could be a cause I suppose. It's informed to nearby regional office but issue still persists. It'd be so well and helpful to get some voltage above 200.
