My name is Ambika and I have a gas connection in Thiruvonam gas agency, at Alappuzha District, Kerala State with consumer no.6878.For the last 3 months I have availed 3 cylinders but my subsidy amout is not getting through bank. As we are suffering from financial problem this is not an easy amount for us to wait for this much .We have already submitted all documents to bank and gas agency.When we approach both they are saying wait! Please take necessary action
