When I click the "Resolve" button at the "Account balance" point (not sure if that's the exact name in English, because I am in Germany) then a new dialog appears and in the new dialog there is a link. You get there to the page you mentioned I guess where you can ask questions, but if you scroll to the bottom then there are "Other Options", and one of them is a "Call us" button. When you click it then you get a PIN and a phone number. Not sure if this is the same in other countries but at least that's what is shown in Germany. I just didn't call yet because I am still waiting but if nothing happens in the next few days then I will call them, too.
