Chase - Freedom Card Review

The card offer good rewards, but when I logon my account last night and saw my chase freedom was changed into Chase SAPPHIRE that I never knew what it's. I called the Customer service, they said my card is SAPPHIRE, they don't even know what was happening, and superviser made a research and said FREEDOM no longer avaiable, my card became chase SAPPHIRE. With SAPPHIRE, many things chaged and the reward program changed. Just want to share this with everyone that beware of that Chase card becomes a bad company.  They should notice the custome before any transition. I will close all my chase card, and looking for a better one.
