Enrolment, cancellation and refunds.
Last updated: 3 November 2026
These terms apply to individuals enrolling on our training courses and certifications. For companies and organisations, the terms are set out in the signed quotation and contract.
Enrolment
- You send us your request via the form, by email, by WhatsApp or at one of our centres.
- We send you a quotation setting out the service, its price, its dates and the payment terms.
- Enrolment is confirmed upon signature of the quotation or contract and payment of the full price, no later than 7 calendar days before the session starts, unless a payment schedule is set out in the quotation.
- We confirm your enrolment in writing.
Right of withdrawal
If you enrolled at a distance (by email, WhatsApp or telephone, without coming to our premises), you have fourteen calendar days from the conclusion of the contract to withdraw, without giving any reason or paying any penalty (Law No. 37-2019 of 12 December 2019 on electronic transactions; for consumers resident in France, Article L221-18 of the French Consumer Code).
To exercise it, send us a clear statement, for example by email to contact@atom-center.com.
If you expressly ask for the training to start before the end of this period and then withdraw, you remain liable for the amount corresponding to the part already completed. The right of withdrawal no longer applies once the service has been fully performed before the end of the period, with your prior express consent and your acknowledgement that you lose your right of withdrawal. This express request is collected in writing, for example by email.
Cancellation or postponement by you, after the withdrawal period
Any cancellation or postponement request must be made in writing (email or WhatsApp). The notice period runs from the date we receive your request.
| Notice before the session starts | Outcome |
|---|---|
| More than 14 days | Free transfer to another session, or full refund |
| 7 to 14 days | Free transfer to another session, or refund of 50% of the amounts paid |
| Less than 7 days, or no-show | Full amount due; a single transfer to a session within the next 6 months remains possible |
A session that has started is due in full. In a duly documented case of force majeure (illness, hospitalisation, bereavement), we offer a free transfer whatever the notice period.
Cancellation or postponement by ATOM Center
If we have to cancel a session, we will offer you another date or a full refund of the sums paid, as you prefer.
Certification exams
Exams take place at one of our centres, in Brazzaville or Pointe-Noire. Once the exam session has been booked with the certification body, any postponement or cancellation is subject to that body's rules. You may request in writing to postpone your exam up to 72 hours before the scheduled date, subject to availability; any fees charged by the certification body remain payable by you. After that deadline, or in case of no-show, the exam is considered taken and is not refunded, except in a duly documented case of force majeure.
Refunds
Any refund due is made no later than fourteen days after your withdrawal request, using the payment method you used, unless you agree to another method, at no cost to you.
