As I hadn't heard anything I phoned again just before 5pm and spoke to a lady, who confirmed that my email had been received, She seemed to think that explaining that it was a technical problem that was being sorted out by the developers was sufficient, but I stressed that what people really needed to know right now is that they aren't going to lose the money they've spent.I was in contact again with the Press Office this morning and at his request sent the Duty Officer an email outlining the issues (and providing a link to this forum discussion). Hopefully I'll get a response soon.
