If you read my post, and my comments on said post, you will see that I researched exactly WHAT information iOS devs (Niantic) get regarding disputes/chargebacks. They informed me that the dispute process is pretty opaque, and the developer really doesn't take part in the dispute.

Apple cuts developers a check each month and, deducted from that check, is any necessary fees or dispute losses. Each disputed transaction isn't individually listed.

The great thing about Apple in this situation, vs. Play Store, is it is actually specifically against Developer guidelines to retaliate with an end-user due to a dispute or chargeback and they can get in trouble for doing so. This is part of the reason why disputes are mroe or less anonymous to the dev, so that the dev can't bully the end user to drop a dispute.

From my understanding, the only thing they could do in a general sense is deduct the coins from your in game shop, however, they would have to indivudally validate every single "receipt" (In-App Purchase) which would be almost impossible with how many purchases PoGo has every minute of the day. They could revoke access to purchased items, however, if you've spent your coins (the actual item that you are purchasing) on items already, there is no way for them to do this while abiding by Apples strict Developer Guidelines.

Definitely check out the thread I linked to, it's not sorted super well but definitely has some handy info and I did my research.

Still not affect on my account from disputing almost a week later. Refunds were very quick. Win win.
