Indraprastha Gas Limited [IGL] — repeated excessive billing by totally ignoring actual usage as per meter

1. Our house was locked for 2 months since we were out of the country. On our return in june 2018, i found invoice no.[protected] dated 20.06.18 for rs. 938.62 which was based on the closing reading as 500.561 which was far far above the actual reading even after receipt of the bill.
2. I immediately contacted customer care and lodged a complaint. On their request, i even sent the meter reading by whatsapp on the number given by them.
3. I later found that the invoice amount had already been debited to my bank account as i had given standing instructions for direct debit. On calling the customer care again, i was told that the excess recovered would be adjusted in the next bills.
4. To my surprise, another bill has been raised and debited in my bank account which has been based on closing reading much below the 500.561 mark upto which igl had already taken payment (Invoice no.[protected] dated 08.08.18).
5. The bill shows nil adjustments inspite of excess amount already received by them. I lodged a complaint well before the debit of the bill to my account. Surprisingly i have now received an email informing closure of the complaint as resolved although nothing has been done.
When called, the customer care every time has the same excuse that they are unable to view details due to technical issue. This is clear cut case of cheating.
