Indane Gas Agency Guru Krupa J.p.nagar 6th Phase — They do not pick up phone

Address: Bangalore, Karnataka

I am having gas connection of Indane Gas from GURU KRUPA gas agency J.P.Nagar 6th Phase.
These people never pick up the phone. I have been facing this problem from couple of years.Once connected it will go till last ring and suddenly next call will say phone is busy.

I also came to know the same issue from other customers too from the same agency. I do not know whether INDANE gas agency is intentional tactics to reduce the number of refill request to sale in black
