Indane LPG — Cylinder gets perished within 12 days for last 3-4 months whereas usually it keeps on running more than 30 days on average

Address: Howrah, West Bengal

I have been a cusomer of Indane gas since 2008. Recently, the gas cylinder delivered at my place gets finished within 12 days for last 3-4 months whereas it usually runs for atleast 30 days. Also, cylinder when delivered seems to be lesser wieght than before. But, when asked , the delivery man is unable to provide weight measurement of the cylinder, though he keeps on insisting for unauthorised "Bakhsish" for delivering Cylinder at my flat. May I know where exactly I can complaint for the same to get the issue resolved? My consumer no. is 010128 and Agency of Indane is "Aladeen", Address being 160, Andul Road. Howrah-711103.
