Maharashtra Natural Gas [Mngl] — no piped gas connection after 99 days of customer number generation

Address:

Pune, Maharashtra, 411013

I had applied for a MNGL piped gas connection in first week of March 2019. My Business partner number was generated on 12 March 2019. I was told a gas connection will be enabled within 90 days after business partner generation. So I was expecting a connection on or before 12 June 2019. Today its 20-June 2019 and no one from MNGL has turned up to give me a gas connection. I made multiple phone calls to the MNGL customer care number, sent multiple emails to the customer care email ID but I think there is no one responsible who owns the new connection. This is totally unprofessional service from MNGL. We are in 2019 and I wonder why MNGL needs 90 days to give a gas connection. How about money that customer pay on day 1 ? How much interest MNGL earns on this amount they get from every customer ?
