It is irrelevant whether he said that or not, because this would need to be possible not right on the first day, but once it's learnt and improved by you as user and performer of the method.
It's common sense that no method will bring you 50-300$ a day from day 0, you need to familiarize yourself with it, learn how to make it better, continue doing it for a while until you get better results.
If you want to be refunded because it doesn't work, you will need to continue testing it, and accept help from the seller for at least a week. This should be enough time for you to reach some success with the method and if not, for the seller to understand and trust you tried your best before you gave up.
This applies to all buyers.
Thank you @Lucas
We actually agreed on that before the scam report, I told him that if he test it and he feels that it isn't for it I will refund him, he actually wanted that. But I guess he is too lazy to even do that .
