Their customer service is worse than Xfinity. National Call Center? It is not “national” at all. It is “international” and they, without a doubt, have a script they follow. I was trying to get a new tank installed next to my existing one. I have called several times and was told “service has been scheduled, someone will reach out”. So far that has not happened. So I am switching providers. Now comes the process of getting their tank removed. Based on existing reviews, it could take a LONG time. DON’T do business with this company
