5 year golden reaper grind ruined by vitalis bug

Saved all my pet from the last 5 years to spam boss logs and golden reaper and ifb title. I had 2 bombi stones and 1 vitalis stone. When I clicked the vitalis stone it vanished and didn’t award me with the pet. Now I’m vitalis off vorago log golden reaper and ifb. Vitalis alone took 700 hours. Lost item claim was rejected. What to do?
