H. P. Gas — delivering the cylinder with 10.2 kgs

Gurugram, aryaveer hp gas service they are delivering the cylinders with less weight as less as 3kgs, have taken the photos of the cylinder which have sealing.in less than 2month we have done with 4 cylinders and i asked my wife to check the weight of the cylinder next time when the delivery boy comes home. He showed the weight from the weighing machine that he bought and so she believed in. When i go back from home, i was still doubt full so we have a weighing machine of our own and when measured it is only 25.7 kgs which is ~3kgs less than what it needs to be. So i have taken photographs and registering this complaint.
