Lost Athena V with Gilded Athena/Emissary Missions due to Server Merge

Is there anywhere I can report this to Rare/the SoT staff? Spent hours grinding to Athena V emissary just to lose the Gilded Athena and Emissary Missions due to a server merge that kicked me and my friend after. I was able to back-record as proof. I just want my Gilded mission back, such an awful way to end an awful year.
