Tamil Nadu Electricity Board [TNEB] — frequent power fluctuations

I am residing in mambakkam for the past four years. Due to frequent power fluctuations, most the electrical consumable and appliances are damaged. Meters are not running and faulty. The eb office at mambakkam (Vandalur - kelam bakkam road) not changing the meters for months together. Raising average billing. Further facing the power issue and no response from eb authorities so far. If requesting to change the good transformer, they asking us to provide funds to install transformer. If rain starts immediately they are disconnecting the eb lines. But ht lines no problem they are all safe guarded by the eb authorities. I request higher officials of tangdeco to take neceeary and quick action at the earliest to resolve the issues.
