No 24 hour service from Enercare

Our high efficienct furnace boiler quit ['after hours', namely 5pm] one winter night. I called Enercare '24 hour' service number at 9:45pm, only to find out that they don't service at night!!! It is the middle of Feb abd we have NO HEAT! The earliest service call is 'between 11 and 3' TOMORROW! We have been an Enercare customer with a service contract since 1987 and paid them a lot of money [and bought this furnace a few years ago from Enercare]. Silly me thinking that the first time we actually need them [besides annual cleaning and maintenance] they FAIL US! wwe have absolutly nothing good to say about this company and we be researching ways to REPLACE THEM. Be warned!
