How to play 2 accounts after upgrading account in Jagex?

[Dunny09 0]

Hi guys, the title says it all. The account manager has picked up that i have 2 active accounts under the same email but every time i try to log into the other account it simply will only attempt to log into the first one listed. Is there a way around this or do i simply add and remove the account i want to sign in with?

 

Cheers
