Yehia provided me with awesome support. I signed up through the portal, but my AppSumo deal wasn't activated on my account yet. Yehia was quick to reply to my support email (on a weekend too) and get my account setup under the lifetime deal. Im up to 10 codes now and considering more. Charla looks like a great chatbot tool with excellent potential! I really like the ticket section of the dashboard and the live visitor metrics.
