I assure you this isn't malicious!

Is there a chance you created multiple accounts?

For example, did you create an account for a free preview of something, or a free course, then create another account using a different email address to make the purchase? 

This is the case in every instance of this happening - you won't see your purchased course when you're logged in using a different email address.

Your two options

We can try two things here:

1. You can try logging in using your other account if you can remember your login details.
2. We can transfer the enrollment to your first account.

Please let us know if you'd like to do the second option; please allow one business day for the transfer.
