Indane — indane gas cylinder

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I am having an account with samaira indane gas agency, noida.
Everytime i order a cylinder, they deliver a cylinder with lesser quantity of gas or a defective cylinder that leaks gas.in mamura, sector -66 noida, all the cylinders delivered are the same. Why is the agency letting these people risk all the residents lives, delivering leaking cylinders.
I have filed a complained to indian oil but appareently no action was taken.
Yesterday, they delivered the cylinder with 2kg less gas than standard weight. I returned the cylinder, then they delivered a leaked cylinder. When i again returned, they delivered a sealed cylinder with lesser gas.
This agency is fraud, their weighing machine is rigged. How can we trust indane, when these fraud agencies are representing them?
Please conduct a proper inquiry, take an action, so that these agencies stop cheating people.
