They told me they wouldn't change my Rockstar account, and I had to recover my Gmail account, which I couldn't do for months. It kept blocking me before, but now it worked somehow. I ended up having to tell Gmail to text me a security code on my phone, so I could type it in again. Afterward, it told me to change my password, and forced me to type in my other email for recovery purposes. I think this whole thing isn't a legit security issue, it's just Google wanting my personal info. I was able to get into my old Gmail account and Rockstar account afterward.
