Mahadiscom / Mseb / Msedcl — faulty meter, no display

Address:

Mseb, pune: consumer no.[protected].

My power meter is not working since june 2018. The display of the meter has gone blank. It was checked by the mseb technician but as they don't have any spares so it cannot be repaired.
After repeated visits to mseb office at ganeshkhind road, pune and requests to replace the meter, nothing has happened yet. They say they don't have new 3-phase meters for old connections.
And since my meter is not working my monthly bill is charged much higher than our regular normal bill.
I don't know what to do or to approach whom...!!!
Will some higher authority or anyone help and replace my power meter so that i pay my normal bill's.
