Yes, I am still getting the emails. However, thanks to Lyp846's advice, I called the number s/he posted and they are escalating the issue for me. Apparently they underwent an system update in May, and that may be what is causing the problem (not actually people trying to get into our accounts). They acknowledged multiple people are having the issue. They don't have a solution yet, but are working on it. I called Tuesday night, and they called me back this morning giving me that update. They also gave me a direct line to call back and a ticket number for my specific issue. They said they will call me and keep me posted on their progress.
If you're having this problem, I'd recommend doing the same thing. They offered to reset my password, but I told them "no," since I've done that multiple times already and the emails keep coming back. They even said that if they reset the password with me, there's no guarantee the emails will stop. So I am just waiting for the issue to be solved, and then I will reset my password for good.
I will post an update on this forum when I hear back.
