Yadu Gas Agency — Cylinder given by the agency are very less in weight

It has been complaint to Yadu Gas Agency many times earlier also, but no response from the distributor has been given till date. When ever delivery person brings the cylinder it is always less in weight & it never works more then 15-20 days. It does not matter to distributor or delivery person whether you return less weight cylinder or make complaints but they keep on repeating same method every time . i am sufferer from last 8-9 years since i came to vasundhra and my connection has been shifted to Yadu Gas Agency Shahibabad (U.P.)
