Talk to a person.

We answer in English or Dutch, whichever you write in. Expect a reply within two working days; a payment problem jumps the queue.

The more of this you can give us, the fewer round trips it takes.

• The email address on your account — not necessarily the one you are writing from.
• What you were doing: the module and the exercise, or the page you were on.
• What you expected, and what happened instead. A screenshot helps more than a description.
• Your browser or phone, if something looked broken rather than wrong.

Tell us which payment method you used and roughly when. You do not need a reference number, and please never send us card details, a full IBAN or a password — we never need them, and we will never ask.

If your bank is still processing an iDEAL payment, that usually settles by itself within a few minutes. Access opens automatically once it clears, so there is nothing to pay twice.

A copy of your data, a correction, or deletion of your account: same address, and we answer within a month. What we hold and why is set out in the privacy notice.

We are not DUO and we are not affiliated with them. Questions about your actual exam — booking a date, your official results, your integration obligation — have to go to DUO directly. We can only help with practising for it.
