After the delivery of cylinder we are allowed to book after 22 days.
After booking they are delaying for delivery from 15 to 20 days,above this the delivering man is also delaying for delivery.I got my cylinder today 17/11/2010,
my booking date was 1/11/2010 and my booking no is 109.All above this, they have given the bill to the deliverying man on 15/11/2010,but gas was delivered on 17/11/2010.When we asked him about this he said that they want two days for delivery.Only this agency has such typeof rules and regulations other agency of Indane are delivering time to time,they are not taking more than two days for delivery after booking.What to do ?.Maximum a cylinder is used 25 days, the agency is taking 40 days how could we adjust this 15 days?. What is the problem with this agency?
