Indraprastha Gas Limited [IGL] — in necessary delay by irresponsible officials of igl

My bp no is [protected]. GI fitting took place on 20/08/2018 and meter was also installed. For under ground connection Mr. Amrender Singh was contacted he always replied that he was on leave. Finally he gave me no. of Mr Aftaar Ahmed then prior to dusshera I approached to Mr Aftaar Ahmed and he said just after dusshera Mr. Gautama will complete the task but Mr Gautam never attended phone call. On the other side engineer Mr Ahmed always gave false assurances.
Then I visited Nanak Puri office and came to know that Mr Arvind Kumar is senior to Mr Aftaar Ahmed. On 19/11/2018 I contacted him and as per his suggestion a WhatsApp message was posted to him with a request to do the needful urgently as it was already delayed.
Mr Arvind also took it lightly and did not responded. Work is still pending. In the mean time online complaints were also lodged but I am regret to say it appears no code of conduct is applicable in IGL.
Would you take any cognizance of my genuine complaint and take stern action against the incompetent and irresponsible officials. I am senior citizen and they befooling me for the last four months.
Please do the needful urgently.
Yours reply is awaited. I found no response whether online complaint or complaint on toll free number.
