Not sure if you got this fixed, but:
Do you have your Pokemon Player ID linked to your account?
If so, did you get credit for participating in the Aspertia season of League?
If so, is your Player ID linked to the same account that your GL/Dream World account is on?
If so, when did you check? I believe the Scizor was made available on the 20th, but some people had to wait a little bit.
If you got this fixed, then great! If not, and everything above is correct, then you should contact the support, but I believe they're out on holiday.
