I received this lovely note from ConEdison in the mail yesterday:
IMPORTANT INFORMATION ABOUT YOUR GAS USAGE
The readings we’ve obtained from your gas meter for the referenced account do not show any usage. This is a matter of concern to us since you may have stopped using our gas or our meter may not be working properly.
If you are not using our gas service and do not intend to use it in the near future, the service should probably be turned off.
