I'm no expert with this kind of stuf, but during this transaction, the worste case is that you'll have to wait 7 days.
7 days is the ultimatum before you can take more/deeper steps.

Try to figure out if it is Nordeus or if the fault are by third parties (like paypal etc.) before you can discover how to get your money back!

Sucks!!! Hope for you that you receive your tokens in a short time! (but most of the time it will)
