USA , #visa administrative processing

Hello . My fiancé on February 4 had his interview and went on administrative processing since then. So on April 22 we got an email and they asked for two additional documents . We sent them and they got delivered at them on may 6. Today I checked the tracking and it wrote refused with that short text . And also it was written that it was updated on may 20. Should we worry. ? Is it still on administrative process? When the visa is denied we get en email right?
