CECOZ review for Marvyn AI Chatbot & Live Chat

Update: After I followed up, Marvyn's founder responded and fully refunded the extra-credit charges ($47.55) as a goodwill gesture, and clarified that the credits were consumed by proactive AI messages sent to visitors (including returning ones) via the Welcome Message and Exit Intent features I had enabled — with a full log available in the app's Inbox. I appreciate that they owned it and made it right. My original caution still stands for new merchants: understand that these proactive features spend one credit per triggered message per visitor, and review the auto top-up setting carefully before enabling them, especially on higher-traffic stores. With that understood and configured correctly, and given how the team handled this, I'm revising my rating.
