HCG Piped Gas Bill Payment

[Nalin Bansal]

I have to make a payment of Rs. 3,000 for HCG Piped gas bill. I am unable to make the payment through Airtel, amazon, park+ or any other app due to the wrong CRN no. Structure in these apps. Also, amazon pay is not accepted on the HCG website. What would be the best way to pay this HCG bill? I hold the following cards:
1. HDFC Millenia
2. Amex plat reserve
3. Airtel Axis
4. Citi business card
