End of Phone Support: Benefit from our Advanced Virtual Agent 24/7!
As of January 1, 2025, the customer support teams will offer its high-quality service exclusively through digital channels, and will no longer offer incoming phone support. See the communication sent on this matter for further details.
Register for our Support platform and log in to our virtual agent to find answers, submit a support ticket or chat with a live agent.

New! Support Platform Help Centre
Having trouble registering or logging in to the platform? The Support Platform Help Centre contains a live chat that will allow you to chat with a real agent to resolve these technical issues. It also centralizes all the articles and videos you need to get the best out of the web ticketing system.
Important note: The live chat staff will ONLY be able to assist you with login issues – any other request will need to be submitted via a support case, once the login issue has been resolved.
