Padawan Sabine shards

Back when the marquee was available, while I was completing Tier 2, the game crashed and sent an error message. It counted the battle as completed but I did not receive the rewards or extra 10 shards. I tried reaching out to chat and support weeks ago but they just kept sending me in circles replaying with non helpful quick fixes. 

If I can please have the 10 shards I lost I would be very grateful.
