Help & Support

Why haven’t I received my account credit?

Your credit will appear on your next bill or statement as 'MixergyExtra Credit'. We aim to apply your credit within the first month of each quarter but sometimes it can take a little longer. For example, if you sign up in October, we’ll apply your credit in January. If you don't see your credit on your next quarterly bill or statement, please chat online to one of our advisers who can look into this for you.
