Torrent Power — Meter running fast high electricity bill charged

Address:

Torrent power limited nature Glory parsik nagar kalwa thane 400605

Old meter is running fast
Request for new meter.
Last 6 months high electric bill is charged,
My consumption & appliance remains same

Why consumer had to pay for meter testing.
Why 3 party is not available for meter testing.

On Torrent website complent is logo, call received but not actions taken. Just requesting to visit office, which is painfull to waste atleast 2 to 3 hrs in queue.
