The course is a group on telegram with a lot of different topics to organize it. When you buy the course you will receive a .txt file which will tell you instructions on how to join the course. If you have any more questions feel free to mesasge me on telegram by the user @aeburrito

Once you buy the Premium, you get access to it forever

No, sorry refunds are not available. But you wont be dissapointed with any of my products anyways 😉
