Indraprastha Gas Limited [IGL] — Wrong PNG Bill

My B.P No is [protected].. I made a complaint to your customer care vide my e-mail dated 23.03.23 in which it was pointed out that I cleared payment for the consumption up to 1564 units against the claim lodged through your invoice no[protected]. In the next bill an amount of Rs.761.59 was claimed showing the consumption as 0 unit. Nobody from your company came to take the reading and the amount was paid by me treating the same as an interim bill. But your next final bill no[protected] had not taken this amount of Rs.761.59 into account. This may please be checked into carefully and the said amount of Rs.761.59 which had been paid to you may kindly be refunded at the earliest.
Yours faithfully,
A.K. Majumdar
