As the author found, support is useless . It took me close to 2 weeks after emailing Tim Cook about the situation, since I was seriously considering an iPhone. Executive liason had it reset for me.
I was able to change the password, login, and the VERY next day the password was changed (presumably from whomever is using it on THIER phone). I've given up. My time is not worth chasing this down.
I may eventually just start harassing the douchebag who thinks they have my email address, but there are like 3 or 4 people whom i get email for. AFAICT every single one is a boomer.
