When you schedule a phone call with Apple Support, you may receive an email saying “Sorry we missed you” even though there is no incoming-call record or missed-call notification on your iPhone showing that Apple Support actually called you.
If this happens, it could indicate that Apple Support has a different or outdated phone number associated with your support request or Apple account. They may have attempted to contact you using a number that is no longer active, is incorrect, or is not reachable from your current phone.
The absence of any incoming or missed-call record on your iPhone is an important indication that the call may not have reached your device at all. It does not necessarily mean that Apple Support failed to make the call; the call may have been placed to a different number.
I would recommend contacting Apple Support again and asking them to verify the exact telephone number they have on record for contacting you. If the number is incorrect or outdated, ask them to update it to your current reachable number and confirm that the change has been recorded for future support requests.
It is also worth confirming the number associated with the specific support case or callback appointment, because the number used for a particular callback may not necessarily be the same as the number you expect Apple to use.
Taking this step should help avoid the same “Sorry we missed you” situation in future and ensure that scheduled Apple Support callbacks are directed to the correct phone.
