Indane Gas Cylinder — about delivery and booking of cylinder

good morning sir,i want to complain u about the ROHINI ENTERPRISES (D-62 FIRST FLOOR DURGA MARKET ' NAHARPUR ,SECTOR -7 ,ROHINI DELHI- 85) .their service towards people is unsatisfactory .people had complaints about weight and leakage of cylinders frequently.although in the cash recipt it had stated to check the weight of cylinder on delivery but the deliverymen says they are not provided weight balance by the agency.i had gone to the authority so many time but the problem had not been sorted out till today.i want u to take necessary step as soon as possible.
thank u
