Hindustan Petroleum Corporation [HPCL] — Not delivering gas & complain number also not registering complaint

Address:

45/c, Satyajit Roy Sarani, Behala Kolkata, West Bengal 700060

My name is Mahua Acharjee, I'm from Kolkata, West Bengal 700060, my HP gas consumer number is 663276, dealer - Deepak Hp Gas Supply & my registered/personal number is [protected]. I'm using Hindustanpetroleum gas, & I've been Harassed with lots of things my agency is doing with me. Very unfortunately this time my gas ended just after booking. I begged to them for delivering the gas fast but they, even after 7 days of booking they're not bringing the gas to me. I've booked my gas on 13th September and requested after 1 day for emergency delivery. I've tried to complain on the toll free number [protected] about 6-7 times but they're not registering my complain. Lastly the putting my call on hold and disconnecting my call from their end. They also not brings weight machine maximum time & because of that I'm seeing my gas is finishing before expected time. I have been also tried to change my agency once before a few months online but because of other agencies not delivering the gas in my pin code (700060), I couldn't changed & registered to my old agency again through KYC.
I can't tell you how much I'm facing the critical situation, & my earnest request to check and resolve my problem very fast (today if possible), I'll be very thankful to you.
