I found this website https://customercaretoll.com and this number 1-833-452-2826 which will connect you to anything from gps support to email support does not matter they do everything. I called it looking for yahoo support ended up with garmin support.
Called them again if they get suspicious of you they will transfer you to the actual garmin number
I just called, seems the number has been disconnected
