Bharat Petroleum [BPCL] — Received a sms of gas delivered without any ordering

My name is Harish Venigalla taken Bharat gas connection during the month of Nov 22 from MARUTI BHARATH GAS DISTRIBUTORS, Bowenpally, Secunderabad.
My Consumer Num:[protected]
Since we are only 2 members, not even one cylinder has not completed yet.
But suddenly yesterday evening i.e.; on 03rd May 2023 stating cylinder has been delivered vide booking reference num.5928.
When we tried calling yesterday to office noone is answered.
Today i.e; 04th May 2023 morning we tried calling at 10.40 they answered and told that due to low consumption they themselves had done dummy booking on behalf o[censored]s.
How come they book on behalf o[censored]s without our notice. We have now a doubt they misutilized by booking with our consumer ID.
Kindly help how to take action against the dealer.
