Remove Creative Cloud Licence

Hi,

I would like to reduce my Creative Cloude Teams Licence from 6 (3 Creative Cloud All Apps, 3 InDesign cc) to 3 (1 Creative Cloud All Apps, 2 InDesign cc).

When I try to remove the 3 unassigned licenses I've got "Please contact customer support to remove this license."

Could you please remove these 3 unassigned licenses from my account or give me an email address to do that?

Thx,

Cristiano
