hi all - I am having exactly the same problem.
I ordered an iPhone 15 Pro Max in Blue Titanium and received a fake iPhone 14 Pro Max - realised after opening the box and seeing a lightning port at the bottom instead of a USB-C !
Reported to Apple, reported to the Police, reported to Barclays.
Nobody cares and i've been told that after two Apple investigations and one by Barclays that no further action will be taken, no refund, no replacement. They hadn't even blocked the stolen iPhone! I'm battling with technical support to get that to happen right now. Crazy situation, i have, like others, a grand loan for a phone someone else is having the use of and i'm stuck with a deadweight fake iphone.
Appalling customer service from both Apple and Barclays frankly - so much time wasted trying to chase for answers of where my iPhone i bought from Apple online store is. Sigh.
I'm really put off Apple as a loyal customer for so long. I hope you guys get a better resolution than i did.
Rob
