Booked a conversation by mistake

By mistake I booked a conversation for tomorrow. Is it possible to unbook it ? I contacted the tutor is that enough ?
Are there any admistrators online that can help me out ?
Thanks for your time!

@Elfgal - Sure, no problem! I’ve now gone in and canceled this conversation. In the future, you can cancel any conversation by going to the Speak page, clicking on the conversation at the top then clicking the “Cancel” button.
