listUnsubscribe issues

Aug 18, 2011 at 6:01 PM

I am seeing weird results. On our site, we have a preferences page where the logged in user can update and unsubscribe their mail chimp preferences for a particular list. When the user unchecks all the checkboxes and clicks our save button, the code sees that all checkboxes are unchecked and calls the PerceptiveMCAPI.Methods.listUnsubscribe().Execute. The output returns no errors and everything seems to be correct. 

Now, if I go to my email and click on the email that has a link to update my profile, I see that my check boxes are still checked. However, if I look into our test mail chimp account, go to lists, and look at the specific subscribers for each group in that list, the email is gone.

Is there any sort of bug with the perceptive mc api with listUnsubscribe? Is there a problem on mail chimp end?
