Mahanagar Gas — Sudden spike in Gas Bill amount

CA No[protected].
I used get the avg monthly bill of aroung 600/- per bill. In the month of Jan 23 MGL team has replaced the meter without me raising any complaint. They replaced the meters of all society members. Now, all members have started getting huge bills since then.
My last bill dated 25th April 2023 has the amount of Rs 3764/-, which is almost 6X of m regular bill
Pls look into this and do the needful to reduce the bill and replace with earlier meters.
