IGL — Charging Amount for no reason

Dear Team

My name is Charu, a resident of A-3/318-319, 1st floor, Unity enclave, sector-28 Rohini, Delhi-110042. Recently, In our area, IGL has started but the executive is charging Rs.450 for changing the nozzle to everyone's house and made it mandatory, then only IGL will start coming to our premises.

Would really appreciate it if you let us know, why this is chargeable?Before that, we were using the IGL Connections in Rohini Sector-17, there were no charges taken by any of the IGL executives.

Here is the IGL representative no:, who is asking for Rs.450 before starting IGL to our house.
