Indian Oil Corporation [IOC] — mathru indane gas supply

Address:

Bangalore, Karnataka

We have buying indane cylinders from mathru indane gas service since 10 years. We shifted our house recently 3 years back from prashanthanagar to nagarabhavi in bangalore. Since then this agency is not supplying properly, they cancel our booking, after it is billed n we receive the delivery message. Again do booking, call them on daily basis, 2 - 3 times a day when we find the using cylinder empty.
This time it's 25 days of 1st booking, 5 days of 2nd booking, am calling delivery person for 5th time today. He's gaming.
We had requested for transferring branch/agency. And even for this they are not supporting the necessary action.
Please let us know the option that we can do.
