Reliance Home Comfort

Since the day I moved into my new house Reliance kept sending door-to-door sales reps. Finally when I decide to change the previous owner's ancient hot water tank from Direct Energy, the service that I get is so bad!!! First, one guy from Dynasty (the contractor of Reliance) comes for site inspection and don't call or anything for over 1.5 months. Then I call them 2-3 times and finally someone comes to change the water tank. Now, the water tank has been changed, but the contractor has not given me the return confirmation form signed by Direct Energy after returning the old water heater!!! And everyone knows what that means! No water heater returned, no stopping the billing. I keep calling Reliance, they can't even find me on their system. I call Dynasty, they avoid my calls. If Direct Energy doesn't stop billing me, I am not paying a dime to Reliance. Why do they sell their product, if they can't give the service? My advise, stick to your existing water heater company, because switching is just a pain in.......
