IOC — EXPIRED LONG EXPIRED TO BE USED FOR DOMESTIC LPG CYLINDERS

Dear Sirs, I was delivered by the IOL authority a domestic LPG cylinder which was marked with D11 ( means the LPG cylinder expired by Dec.2011 but it is half past 2015.) I asked the delivery man to change the cylinder. My booking was cancelled and again against my fresh booking I was delivered with the LPG cylinder marked with C11 (The Cylinder was to be used up to Sept.2011.older than supplied earlier) I complained through my mail to IOL Kolkata LPG in charge also the IOL Kolkata area Manager. Nothing solved and replied. Also tried to contact the said offices over telephone provided at the IOL site, but all the telephones were non responsive. I tried to contact through mail and also over telephone to the distributor it also non responsive. Being at the age of 72 where to go to solve the problem that is to exchange the long expired to be used cylinder with full load?
