Spent 100$ on an amazon refund service with him, he had good feedbacks. He didn't scam me to begin with, he actually was trying to complete the service (I got emails from amazon that confirmed he did try), but he failed. Now that he failed he didn't return the money (as his policy) and will not respond.
Be warned, do not use this guys service. I have used other vendors for this service before and never had problems.
out of curiosity, what did you try to return?
