Splintered Sparks of Shadowflame never received, not dropping.

I've completed Power Unified. I've done the Loamm weekly rep quest every week. I've done at least two full raid clears and 8 M+ dungeons every week.

I have never received a single Splintered Spark of Shadowflame. I can't upgrade or craft new crafted gear. I've submitted several tickets to Blizzard and receive nothing but automated responses.

Has anyone else experienced this and fixed it? I don't want to think I'm doomed to having all crafted gear removed from my progression for this season.

Edit: To everyone telling me to search my bags - I know how to search my bags and bank. I wouldn't have posted if it were as simple as ctrl+f.
