Account Security Support is open from 9am-6pm (Central European Time) Monday to Friday, and can be contacted via the webform here.

In all cases, please only use the registered email address to correspond with this department, and never use more than one email address as it can greatly increase the time taken to deal with your inquiry. If you cannot use the registered email address please mention it in your email.
