Maharashtra Natural Gas [Mngl] — connection not done since 4 month

Address:

Pune, Maharashtra, 411061

Payment made on 4 oct 2018 & since that day there are many complaints raised from my side & so many calls are done to mngl chichwad & shivajinagar office.
But there is no outcome of that & till[protected] gas connection not yet done though i have paid 5500 rupees deposit to mngl.
Services are not organised & contract peoples are invoeved in it which are not at all accountable & no control on it.
