I had this problem with CVS and when I called to try to straighten it out, they told be it was bcause the eRX would not go through on their side and the CVS systme defaults to fax Had to scream bloody murder at both CVS and beseech AC to help, which they did
the AC person had to open a surescripts case and something on the CVS end was not updating
I don't know how they fixed it nor don't care but it took a lot of calls and complaining.
