Did not get the free champ

Don't worry about not having it yet. As Stated in the stickied post at the top of the Help & Support Boards, the Mystery Champion is still being handed out.

The post: Pool Party Rewards Distribution [On-going]

Here is the snippet about the Mystery Champion, and the Requirements for getting it, and the note that the rewards are still being handed out:

#Level 3 (con't) -- Mystery Champion

• Any account level is eligible
• You need to have registered your Facebook account to the Friend Discovery feature in your Friends List by June 28th 23:59 PDT, and remain registered for 24 hours. You did not need to have added any friends using this feature to be eligible.
• If you have less than 10 champions left un-purchased and therefore are ineligible for a Mystery Champion, then you will be awarded a Mystery Skin instead
• This reward is still currently being distributed.

Keep an eye out on that post, they will update it once all the rewards are all handed out.

No one's gotten theirs yet it seems

some people have, its all coming out in batches, you cannt expect them to give out millions of champs/skins in less than a day thats impossible!

Haven't received mine. Glad I'm not the only one. :)
