Can't Purchase Kiosk Exam

Hello,

I've been struggling for the past 12 hours to purchase the EX405K exam but without luck. Every time after I select the exam and hit login I just get "You have no items within your Shopping Cart." and searching trough the catalog after that doesn't return any results.
I have raised a support ticket (documenting all the steps and even adding screenshots) but no one bothered to answer for 12 hours.
The annoying part is that my colleague managed to purchase the EX436K exam and he also has the options of purchasing the EX405K one.
So far I never had any issues when I was using examlocal ..
I'm quite frustrated now as I'm in a bit of a hurry.
