West Bengal State Electricity Distribution Company [WBSEDCL] — faulty meter, high electricity bill

Before 3months i applied for faulty meter replacement and for providing modified bill. But not yet no modified bill is provided by wbsedcl, faulty meter isn't replaced. Company peoples are coming to disconnect the supply. I contact to the local wbsedcl office many times, they assured to replace the meter. But no necessary steps were taken by them. They providing very high electricity bill.
