Account email change

Hello, i tried to change the account email and i am quite sure i entered it right. Then i saw it is changed but it is missing one "dot" in the mail name.
And i am not sure did i missed the "dot" or it is some bug and it shows it without the "dot". Also i can change it again after 7 days, but i want to activate the "two factor authentication" now.
I also tried to create a ticket from the support section, but it was saying "ilegal characters" all the time, thats why i am creating a topic here.
