The steam boiler in my basement is not working, none of the radiators in the house are not emitting heat, even when the thermostat is set at 70 degrees. 

The gauge was installed a few months back, it is blinking, showing the number 87. The water level is than half. My children and are freezing right now, I left a message on your answering machine, so far no one has called back. 

Please send someone over to check the boiler. 

Thank you,
Jameela
