Ensure that you are checking the Transactions tab when you are logged into your Waves wallet, since the main assets page does not list any information related to Waves tokens.   For those, you need to go to the Portfolio tab.    Sorry for that very simple observation, however many people who are unfamiliar with the Waves wallet do miss that point.    

There could be a delay between the time you get your confirmation email and the tokens are actually sent to your address.   You might need to way 48 hours or so before they arrive.   If they do not arrive, please open a support ticket from your Incent Loyalty account page.
