Accidentally submitted level 100 Sableye to Gem collector

[Banbiko]

Hello, I seem to have accidentally given away my lv. 100 PvP Sableye that I just bought to the gem collector. 
I don't have any pictures of that Pokémon, but the Pokémon with the OT is owned by Banbiko.

ID: 86404960

I really hope this would return.. I promise to be more careful next time.

Follow this, I caught a new Pokémon. 
 This is the new Pokémon I just caught to replace the one I accidentally submitted.

Hi bitterblade, Is there any way to retrieve my Sableye? This Pokémon has quite high stats and has been trained. I hope you can help me get it back.  
Looking forward to your reply.
Thank you and good luck.
