I've been with iPower for a very long time for hosting my website and email servers. But I keep having problems with the web site and email servers. When I contact customer support asking if there is a problem, they ask me for gobs of information I don't have and then close out my support ticket. Over and over.
Never have this problem with TMDHosting. They actual read my support ticket, think about it and give me a thoughtful answer. So I'm starting the slow process of moving all my web sites and server off of iPower. <sigh>.
Customer retention is a big deal. I wish people would care more about my business.
