Apple support seems to be such a hit or miss these days.
I have the same issue with the sport band that came with my watch. First rep bumped me to a senior advisor, which isn’t surprising, but the senior rep had me describe issue numerous times and said she has to get engineering involved and asked that I upload pics and videos of the issue - all this for a band…
I did all that and the rep called me the next day as scheduled to follow up - couldn’t hear each other so she left a vm saying if I need further help to call in and get another rep.
I called right back got another rep who also escalated to senior advisor. The senior said she couldn’t believe what the first senior adviser made me go through and simply asked for my address and proceeded to send me replacement band, shipped out within an hour.
What a difference a rep can make to the support experience.
