I logged into the AC portal to update CC info and saw that we'll be charged a $150 interface fee for our link to TotalMD on 1/1/17. I called AC to ask about this and was told it's required to keep our interfaces. I asked if we don't pay it, how can they turn it off? Because the interface "files" exists on our computers only. They can't remote in an turn it off. Or is that some other way they can do it? I asked the sales person this and he doesn't know how it works. Anyone know?
