Just an FYI - There is no need to put in duplicate questions in the forums, since the same people usually see most of them. To tag other groups or people, use the @ and the group name like Robert did above. The post will then show up there too. I will mark the other two posts as dupes and link to this one. You can delete those too if you want. Always better to keep one post so all the answers are in one place.
As far as renewal, I think you typically have to go through your customer rep or local distributor.
The page https://www.arcgis.com/features/plans/pricing.html has a link at the bottom for "outside the US"

edit: there is a little more info in the other posts, so you can maybe edit this one to include info. Make sure not to include any personal or customer number specific info.
