Enwise Home Services No Longer In Business

My initial dealings with Enwise were great. However I was told I would save on water with the Tankless water heater and am using way more plus it doesn't maintain the temperature at lower temps. I called to say I wanted to switch to a tank, still with their company and now 4 weeks later I have yet to make any progress....they say they will schedule a switch, promise someone will call within 30 min and still no call. When I call the office the person who answers can only send an email for someone to contact me. Requested to speak to a supervisor, was told I would be contacted within 24 hours. It is now 5 days. I have been totally disappointed and with I had read these reviews prior to starting with them.
