Less weight of gas cylinde

I am consumer of LPG, Indane through Sona enterprises, A-72/2, Masoodpur, Vasantkunj new delhi-70.My consumer number is 25939.Since past few months i have been observing that my gas cylinder gets over before the normal usage time. Today while taking deliavery i insisted the the delivary boy to weigh it he some how tampared the weighing scale and showed me right figure where as later when i got it maesured through a genuine scale it was weighing 5 kg less. This is been a regular feature since past few months .kindly look into the matter and do as required or else i hav to approach other related forums...
