Related question, which has never been answered by OpenAI: Is it really not possible to change the email, name and phone number associated with an account?.
Btw, I’ve once tried to delete an account, which I created with the same phone number associated with my main personal account, and the bot told me that, once I delete the account, I can’t recreate it again. So, that’s why I didn’t delete it - so OpenAI must save the info about previously deleted accounts in order to do this (is this compliant with data privacy policies?). Originally, I wanted to delete it in order to recreate it with a different phone number, given that we can’t change the phone number, email or name, because that account was supposed to be our work account, which should be independent of my personal account.
I’ve been waiting for OpenAI to help me for more than 1 month. OpenAI has not given me any support since I started to use their API a few months ago, although I haven’t yet set a paid account, and that’s probably why, but I wonder if OpenAI also doesn’t care about you and your problems even if you have a paid account. That would be very very disappointing to say the least
