Hi. Sorry to hear that you’re also having this issue.
Firstly, I just want to confirm that you received an 15 Pro Max, instead of a 15 Pro? Was it sealed?
It’s interesting that you’ve received a higher model than the one you ordered and they’re still not interested.
Secondly, you mentioned that the box had been tampered with. How do you know this?
As you can see from the earlier posts on this thread, none of us received a resolution from Apple customer service. We were all told that they’d completed an investigation and found the correct device had been shipped and therefore declined a replacement.
Apple will not provide any information regarding these investigations, or their order fulfilment processes. They will not track the device you were supposed to receive nor will they trace the origin of the device you have received. They are not able to block phones that haven’t been activated by you. IMEIs cannot be blocked unless you know the network that the phone is active on (if at all).
Those of us who were able to get our complaints understood, did so via the Apple feedback channel, or by emailing the CEO.
Im conscious that this thread is monitored by Apple and have seen posts removed. So the best advice I can give is to read each of the comments on here, be calm and concise in any communication with Apple and raise it to the highest level. I hope that you get someone to listen to you and resolve this issue.
