I need help please, i bought this at target but i just cant find my receipt got the box and all the accessories.

Please try cleaning the charging contacts on the earbud. You can use a toothbrush or cotton swab with rubbing alcohol. Dry with a cloth or tissue before attempting to charge the earbud.

Feel free to reach out to if the issue persists.

Just an FYI: Target can typically look up your receipt if you bring the same credit/debit card you used to buy the item.
