Reliance Home Comfort

Came home december 28 furnace not working and home 5C. Called reliance homecomfort and had service appointment for december 29 between 1-5pm. December 29 called reliance 3x to confirm if tech is coming it is already 5pm and they cannot get hold of their tech and then asked if i want to resched for tomorrow and i said no. Tech came after 6pm and said need to order Surface igniter and promised it will be available January 1, 2018. Considering January 1 holiday i already conditioned myself that service will be done January 2, 2018. January 2, 2018, no call received from reliance or tech for any updates. Called them x3 and spoke with CRS supervisor saying for sure Jan. 3 first service call in the morning tech will be in my home to fixed the problem. January 3 @ 930am still no call for update, called reliance and able to connect with tech saying give him 1 hour to get parts. Do not trust them anymore, cancelled service call and called Aire Max and came with parts and fixed problem in 30 minutes. I do not know how reliance homecomfort is getting their parts but not to get surface igniter between december 29-January 3 is uncomprehensible. Very Unreliable Reliance Homecomfort. Cancelled my monthly service plan, what a waste of money and time.
