Bharat Petroleum [BPCL] — delay in delivery of refill cylinder

Address: Mumbai City, Maharashtra, 400092

I had booked gas cylinder on 14 of december 2019 booking no. 118852 but till now i did not receive cylinder. I spoke 4 to 5 times on gas agency they give same reply every time that you receive it tomorrow or day after tomorrow but today they give another reply that delivery man named rajaram not deliver your cylinder saying that customer (I) not receive cylinder without bills. When i talk with rajaram on his mob. No. [protected] you book yesterday means 20 december.
Since last 7 days my family eating outside foods all o[censored]s being bored with outside foods.
In metro cities like mumbai if they are unable to deliver one cylinder in 9 days.
I want to know what type of service bharat gas provide to customer???
I am your give it up customer.
