Like many folks, I have a theory
Apple restructured - instead of having an overall "Support" department with "divisions" within, they now have support IN the different product development departments = 'engineers/developers' & support specialists under the same management
Thus, reporting an issue with a support specialist MAY reach the PTB over that specialist by using
Product Feedback - Apple
and choosing "Other" from the [Feedback Type] menu
I may be overthinking though
Anyway, any problem with physical Retail Store should be handled IN PERSON with the Store Manager
Online Retail issues should simply call 1-800-MY-APPLE and ask for "Customer Relations"
(seventy one, may he Rest In Peace, once reported that he actually struck up an email relationship with the ExecVP of Customer Relations in Austin over some incident)
