Look, everybody and their auntie pre-ordered the new iPhone this week. That is normal. What is not normal is opening your statement and finding charges you never made sitting next to it. That is what is happening to a bunch of Hongkongers right now, enough of them that two major banks have opened investigations. One user online said their card got hit the same day the pre-order went through, which is the kind of timing that ruins a good mood fast.
Here is the part that is actually funny in a grim way. You did the responsible thing. You used your real card, on the real Apple site, at the exact hour they told you to, so you would not miss out on a phone that will be in every shop window by December anyway. And that is exactly the moment someone found a way to skim you. The banks are investigating, which is the correct move, but if you pre-ordered this round, do yourself a favour: check your statement line by line before you just assume it is all iPhone and nothing else.
