Email change / need help

[Tripping]

Hello everyone.

I'm like 1 minute newbie to the forums, a very helpful moderator suggested to post it here, hopefully this is the correct section for this type of problem.

Here it goes, i want to change an email address on one account for the other one, basically i made new one cause of the 30 days no name change thing, couldnt wait didnt like the username quite a lot. I know multiple accounts are bannable, however i only made new one for the username and tend to keep this one for good, tho i want to retake the original email address i have on the first one to the second one, but whenever i try to change it it says "relog with new email address" when i log out cant type the email says i need to type the username, i relog again still the same email nothing changed. I wonder if its possbile to even delete that account and put that email address on the one, which i will have for rest of the time being on faf.

Will give account details if its possbile thanks in advance.
