Martian promotion

I contacted cadbury to ask them where can I get all 5 martians that they are promoting as the engen garages I went to told me that they only had all 5 martians on the first day of the promotion and not again and also the office gets locked and time for picking up the figurines is between 9 to 16:00 and I work between that time they promised to get back to me on which they never did
