Humble Bundle gave me the wrong code for my purchase. What should I do?

In some very rare cases, Humble Bundle may provide you with the wrong code for your purchase. For example, you may have purchased Tier 3 of the bundle (which includes all courses) but received a code for Tier 2.

Unfortunately, this part of the process is entirely controlled by Humble Bundle, so we are unable to do anything regarding this situation. Please contact Humble Bundle directly via their help desk for assistance: https://support.humblebundle.com/hc/en-us/requests/new
