Padma Gas Agency — Delivery charge

The delivery person is demanding money all the time for delivering the gas even though the charge is already included in the price. When we don't give them the money they demand, they behave indecently. I have been experiencing this issue for a long time and even took it to the knowledge of the Manager (Kumar) of my gas agency (Padma). But it has gone in vain as the same thing continuous and also they support their people without taking an action on them. My Consumer ID is CX15735529. Please look into this issue and take a necessary action to prevent this in future.
