I don't know where to post this issue, but I want to upgrade from Pro 7 to Pro X10 and it say it cost me 139,- but when I add it to basket and go to checkout I have to pay the full price 299,-

I have register all my products and it shows in the list, pro 4 to 7 plus bought upgrade to Designer 10 (did not know it was 32bit) and use the right email address etc. and it still show the full price, how do I contact them?
