Reliance Home Comfort

I have been renting the water heater from Reliance and recently noticed that there was a substantial amount of water under the tank. I called their service and scheduled an appointment that was given to me a day and half later. When finally the guy showed up, his first words were oh we will need to change the vent and that will cost you about $300. Then he goes on about how the tank is actually leaking and he doesn't have one today so won't be able to fix. Terrible service... So much for "peace of mind". When I told them I will buy my own tank they are trying to ding me $40 for an "account closing fee and inspection". As far as I am concerned they haven't provided me with a reliable water heater...
