Bharat Petroleum [BPCL] — Sms says cylinder delivered but not delivered actually

Address: East Tambaram

This happens each time I pay the amount online. I get the sms as cylinder is delivered, after two days after calling them the agency says sorry and delivers it.
I guess the following reasons:
1 The delivery guy and agency are hand in glove in this.
2. They are interested only to deliver quickly to consumers who pay cash on delivery and not online.
3. When consumer pays online the money goes directly to BPCL account and not to them.
4. They have a short period by which they are supposed to pay the cash collected to the BPCL account.
5. Between this time, they are rotating the cash for quick interest (day money market trading).
6. If 100 cylinders get delivered in a day they get cash of ₹90, 000. They or the delivery guy rotates this cash among needy shop keepers for high short term interest.
7. They want to punish consumers who pay online by delaying the delivery, so that they stop this online payment.
Dangers to consumers:
1. If the delivered cylinder is malfunctioning and bursts in the other house (remember that your cylinder goes to some other house, while you get sms of delivery) you the consumer will be questioned by the police if any death or injury happens. It is your cylinder in another house!!!

BPCL has to adhere to OTP pin concept while delivery as done by Indane urgently.
