When your home gas bottle is finished, how do you get it?

I also use gas installations at home, but I never change them myself, because I know that this is quite unsafe. Therefore, usually when I have a need to replace something related to gas or some kind of breakdown occurs, I contact customer service to help me with such equipment. I think it's best to let professionals do this sort of thing.
