Indane domestic gas cylenders
Info.needed- after how many days 2nd cylender can be booked

Dear Sir. We are having a connection of indane gas since last 35 years. we have 2 cylenders with us. Generally one is in use and other one is a stand by due to ertic supply from the company. when ever we go for booking for cylender company people tell that we should come after 21 days from the taking delivery of the cylender. I understand such time limits are removed by the company. will you please help us to give correct picture of this problem? Regards.
