Gifted a friend a 1000 coin lifeline pack and never was received

InfinitLeee  Are you meaning the Lifeline Edition pack, or was it one of the Apex Retro/Event Packs?

If you could, can you also share a screenshot of which pack you're referring to, (especially if its not one of the ones mentioned above), as well as a screenshot showing that your friend isn't eligible to receive the gift, as they "already own" those items?
