Rappel important : le soutien par courriel a été remplacé par le système de demandes de soutien en ligne

Chère cliente,
Cher client,

Nous tenons à vous rappeler que le service de soutien par courriel du Service à la clientèle et du Centre de soutien a été remplacé par notre système de demandes de soutien en ligne et notre fonctionnalité de clavardage afin de vous fournir un service plus rapide et plus efficace! Par conséquent, les demandes soumises par courriel ne sont plus surveillées ni traitées.

Si vous ne l'avez pas encore fait, inscrivez-vous à notre plateforme de soutien pour facilement soumettre, modifier et faire le suivi de toutes vos demandes de soutien à partir d'un seul emplacement en ligne. Vous recevrez des notifications dès que vos demandes seront traitées par nos agents de soutien et que vos problèmes seront résolus.

Nous apprécions votre collaboration et sommes heureux de pouvoir continuer à vous servir.
