Indian Gas
Delivery of Cylinde

I have gas connection of Indian gas from Punia gas agency Sec. 32 Chandigarh and every time they don't deliver the cylinder in time even they take 20 days when i call them then ans. is today is dry day, aaj delivery nahi aai, our delivery boy is already gone to your place and he reports us that he had delivered the gas. But I did not receive any cylinder. It means they are black the cylinders somewhere. Is there any one how can check it honestly
