I am a customer of Rani Enterprises, No.44,PerumalNagar, II street, Nanganallur, Chennai, Tamilnadu-600091, India for supply of cooking gas. The never lifts his phone whenever he is called for booking a refill. For instance I am calling him for the past two days and I could not get them over phone. Whenever I call them I get a recorded message saying that the number you are calling is busy and try after some time. Actually my fingers got paining in dialing their number. The Indian Oil Corporation has also not provided any information for contacting them to book the consumers grievances against their agents. I need help in this matter.
