Mahadiscom / Mseb / Msedcl — Meter failure since last 2 years and more

Consumer no[protected] our meter is in faulty since last 2 years and more and we have given a written complaint also to the Virar office of MSEB but they have only one answer that meter is not in stock when the meter will come from head office we will change it and for these they have fixed our bill amount to Rupees 1390 (168 units) by taking average
Since in our house there is no AC gijer then also since last 2 years we are paying the bill fixed by them on a expectation that they will change the meter.
But now the limits has crossed thay have created the bill for 368 units and displayed meter status normal as they have not yet change the meter
So please help us for these problem.
