Yeah this really sucks, especially for something that was aimed at newcomers to the portablizing scene such as you and I. I had the same issue, posted in Discord, emailed and contacted numerous people via the forums. In the end the only thing I could do was raise a dispute with my credit card company. They were very helpful and were able to do a charge back and I got a full refund this way.
I would recommend doing this if you used a credit card. Short if this I'm afraid it doesn't appear that anyone else can help.
