At the top right of the website, you’ll find the "Contact" section, where you’ll see all the instructions to reach me. It’s very simple: download Session, enter the ID provided in this section, and send me a message. Can I request a refund in case of problems? Of course! Send me a photo or, preferably, a video showing the problems you’ve encountered with one of my products.
