Mahanagar Gas — Complaint regarding faulty meter bp no [protected]

I have already lodge complaint from my login on 02.05.2021 however no response received from your end.
Hence today i have contacted to customer care but no positive reply received.
After closing yellow color knob my gas meter is continuously running, hence i have received bills much more than my consumption.
It is requested to kindly depute your technician for meter checking and replace the faulty meter.
