Even after calling the agency several times, they didn't deliver the gas. And it is their not for the first time that they behave this way, it's been like these all time.. Now i am forced to change my subscription from indane to some other available gas agency which are easily available... Very bad agency. Kindly take action. Am also taking legal action against this agency, by the rule they should deliver within 15 day, so that they behave in future with customers..
