I just went to the Cash shop and bought the Delish Noel set, after buying it the site gave me the Service Unavailable page, and it purcahsed two of the Noel complete sets, instead of only the one I intended...I dont know of there is anything that can be done...though I wish I had the CSC back...i was intending to pay for CWs I was waiting on.

pretty sure they can take the items and refund your csc, write a ticket!

Just got done doing so. Though I think in the past it couldnt be restored...maybe I am wrong
