I tried to change my old email address (that old email doesn't work anymore, and it was the same email address that I used for my facebook. I log in GMATclub via facebook login) to my new email (my current email) but it wouldn't let me, as it said that there's an account for it already. I think I accidentally used that email for another account when I logged in "sign in with Google." I already deleted that GMATclub account, but it won't let me change the email to that.
In addition, when I tried to change the email, it tells me to use a current password to confirm the change, but because I logged in through my Facebook account, there's no "password" associated with it. And if there's a password associated with it, I can't retrieve the password from the email because I don't have access to my old email address
I activated the 7 Veritas Prep mock exams from the kudos rewards system, and I believe that link might've gone to the same email address so I don't have access to it.
Who should I contact for technical help, and is there any way to fix/make these changes?
Thanks,
