[Resolved]  Mahanagar Gas Limited — Indefinite delay for new connection

I had requested for PNG at my residence in november 2012 and I had even submitted my cheque for the same cause(of Rs.6250) on 24/12/2012 and in november,2012 i was said the same would be done in 45-60 days but it dint happen so. i called a help line and a complaint no. of 1351771 was generated on 19/1/2013 and a new complaint of 1378961 on 19/2/2013. For my first call to help line on 28/3/2013 i was informed that m cheque was not passed and my pass book shows the cheque was encashed on 9/2/2013 and my request number there in was 1417287. The guy whom i called next time was named "ovaish sheikh" on 1/4/2013 who generated a new complaint /request no.1421476 an he said "within next 15-30 days job will be completed" next cal was with "manvel noronha" on 6/5/2013 and he just said "he will coordinate to service and let me know".but no response further. the next call was with "sunil sharma" on 9/5/2013 he said "it was under process". after 5 days,on 14/5/2013 i had talk with the same person,"ovaish sheikh",and he organised a call back from company on 14/5/2013 and it was from higher authority manger named "vicky sharma" and he gave a commitment "anyhow final date 20/7/2013 my connection will be done." on 16/9/2013 "mohin uddin" picked up the phone and arranged a call back and final date on 30th october and call back was about to be there in 48 hrs but that dint happen till today. whole building of ours has gas lines(10 flats from 12) but still our request is not being proceesed . please provide me with guidelines or should i visit a physical consumer court for this case?
