Dear sir & madam, i have purchased gas cylinder from bharat gas distributor located in sadat, saidpur pin code 275204 on 12/04/2016, he has not yet given me any official papers like invoice passbook for refill nor my consumer number. I tried to call many times to owner but he also ignoring my calls and i have refilled the cylinder in last month but subsidy is also not yet credited in my account. Some where i feel that they are harassing me mentally the owner name is mr. Jaiswar. I called him many times but he answered me once and assured that your problem will get resolved in two days but he has not taken any action and now he is not answering my calls. Kindly suggest what step can i take.
