Woltec,
The Lucio emote was not intended for sale with OWL tokens and is a mistake which they will fix soon .If you made an OWL token purchase on the Blizzard online store, and you’re not able to use it, Blizzard Customer Service might be able to refund you the recent OWL token purchase (click here).
Any OWL tokens earned through watching OWL or purchased later than 14 days cannot be refunded. Any skins purchased from OWL tokens cannot be refunded.

On a side note, the Lucio Dance Party emote (and all other All-Access pass items) can still be obtained if you purchase the Overwatch League All-Access Pass which is still available to buy on Twitch.
