Not yet. I've e-mailed and they have received my e-mail. I'm currently in South Africa and don't plan on making any SA-Europe calls from here, especially since the call is likely to be long and my Spanish isn't great..

There's a (not very efficient) UK local number which I can try when I get back. In the meantime, it's 2018 and I can think of no good reason why I should have to call. Efficient IT ought to deal with the matter. And IB really should appreciate that not all their customers have first and second surnames. Making a first surname part of their 'security' process is absurd for those that don't have them.
