Kalyani Motors — Monthly gas cylinder delivery and delivery boy behaviour

My consumer number is 53432214 with Manav enterprises as teh distributor : I had booked the cylinder on 31-Aug-15, the bill was generated on 3-Sep-15, and till date the cylinder is not been delivered. When i contact the distributor they say its the responsibility of the dispatch incharge Shekar. When i call the dispatch incharge Shekar, he says the load has not arrived hence the delivery is delayed. IS it that bad since one month. this has been an ongoing issue with bharath gas. my parents who reside in the same compound do not face such issues with HP gas and my aunt who reside in the same compound does not face such issue with Indane gas Please let me know is this an integrity issue with ppl in the company or is it a genuine issue, which i suspect I get the cylinder on calling the concern ppl. if i do not call them the cylinder is not delivered. should i call ten thousand people every month to ensure the cylinder is deliverd. please advice. Also the delivery guy Jaipan is very arrogant with us. he demands Rs 100 for every delivery. how should this issue be resolved. please help us.
