Indane — Not getting cylinder delivered on time

I am Mohan from Bengaluru Customer ID:36645 & my agency is DEVAGANGA Associates. Am having single cylinder connection, I got my last cylinder delivered on 16/01/2015 against d date of 13/01/2015. Then I booked for Cylinder on 03/03/2015 ref:451165. Booking has been cancelled on 18/03/2015 again rebooked on same day & visited agency on 22/03/2015 but they not given any valid reason for cancellation but told me that Bill has been generated will be delivered in a day but it was not. When again visited today 27/03/2015 they are telling me will be delivered tomorrow. Imagine how can I manage with single cylinder for 3 months having 4 family members. Request you to support me in getting double cylinder connection & delivery in on time without delay.
