NyxUlric.Service misleading scam

Scammer's profile link:
NyxUlric.Service
Explanation of the trade: I purchased a method on how to do my own twitch primes with a "Key of creation" as you'll see in the screenshots below. I gave him the money, he accepted it.
How they scammed: There was no such "Key of creation" or anything similar of the sort. The way they explained it to me, prior to telling me the method, was misleading and shouldn't be stated in such a way.
Proof that it's their Discord:

I have a screenshot of the method if needed. The deal was done on August 19th and we tried to discuss a solution to this but could not come to an agreement.
