I have been emailing them about mine and they said this regrading my CAS and it might apply to more people here
"We have now received and processed your results. As we are now under UCAS embargo, we are unable to process your offer acceptance form at present. As soon as the embargo lifts, we will be able to do this and proceed with your CAS."
I think we have to wait for embargo to end. I don't, however, know when that is! Anyone else know?
