unable to unsubscribe from the panel station

<p>Hi </p> <p> </p> <p>I have tried on numerous occasions to unsubscribe from the panel station and it's quiet frustrating as the app does not work nor does it give the option to unsubscribe and would like my email address to be removed from their database. </p> <p> </p> <p>Thanks</p> <p> </p>
