Indraprastha Gas Limited [IGL] — old rubber tube at instalment of new png connection

My bp no. [protected] which new connection installed on 08.01.2017. Now few days ago (Like 5-6 days) your staff come at home for checking and said that your rubber tube is very old (Because print date is 12/2009) and change, but my connection is installed on 08.01.2017 and i don't check print date on rubber,
Because your staff fix the old rubber on time of installation.
So please change my rubber earliest without any cost before any misshaping.
