Indian Oil Corporation [IOC] — gas late delivery

Hi
Am from hyderabad. My consumer number ‭[protected]‬. We are not getting gas delivery on time it is taking 15 to 20. Days. Agency guys response is very bad. I had called them from last 1 week for delivery of cylinder still no response. Last 1 week they are telling the same twomarow it will delivered. I got a message that door closed. With out coming to our house they said it. Don’t know what to do. Hope you understand customer problem. Otherwise we need to shift to other gas company. Don’t know whether i will get response or not.
