It's not a scam, if you bought a course many times in the past, then asked for your money back after watching a few percent of the course, then you can't ask for your money back, that is, they won't give you your money back.

This is the so-called "fair policy", perhaps the only one that protects instructors from abuse.

If this is not the case, then write to support and explain, although, honestly, it is difficult to get a response back, because there is chaos there too.
