The solution is to have a sound recording device nearby and record the call as soon as you hear it's from Apple. Or record the calls on your phone if it allows it.

It should be a starter kit of any developer for Apple platforms, just in case, you know.

(Recording calls from numbers you don't recognize as a habit is not that stupid. Who knows, one day it's a robocall, another day Apple, still another day some death threats you'd want to hand over to police.)

It is illegal to record phone calls in California without obtaining consent from all parties. If you ask Apple for consent, they will hang up.

If you record the conversation without consent and shame them on the Internet, you can be sure Apple will sue. It is one the most litigious companies in our industry.

This is it. Go on record or shut up. Send an email or shut up. Don't tell me you tried to inform me of anything otherwise.

They didn't want to go on record for such an innocuous thing — why? Because they know a paper trail could hang them to dry in a court? Okay, now we've got an INTENT here.

What if I don't record them, technically, but put them on a speakerphone instead and let two to three reliable witnesses listen to the entirety of it?

Ironically, as far as I know, at least in some countries they record all their support calls ("for quality improvement") and you either have to agree to it or no support for you.
