Well, you agreed to pay .292 to get your transaction confirmed. Your transaction got confirmed. So, you owe the money. It doesn't matter how it gets done, you should've done your own research before you agreed to this deal and get taken advantage of.
The fact that you're not paying actually makes you a scammer. Your transaction got confirmed due to it being accelerated which needed to be done one way or another. Nachius' behavior is clearly predatory, but you're a noob so you should expect to get preyed upon and do your research before believing any some smooth-talking charlatan who comes your way offering a 'solution'.
I agreed to pay that amount because the user told me no tools work "
ViaBTC and all of that shit does not work" , so I thought this would be the only solution.
But user was lying and had the intention to make more profit out
