cannot activate

I activated it according to the URL below.
Login on ubisoft is also successful.
URL: https://uk.gamesplanet.com/support/14-activations/110-activation-with-ubisoft-connect

I was redirected to a store page that said Login to Ubisoft.
There was no "Activate with ubisoft" text there.
I can't even get a refund.

Please support
