This guy is a Fraud!. Plain and simple.
His products do not work and he doesn't refund so stop with the bullshit. The two accounts vouching for you are low comment accounts and i doubt they have been purchasing from you for a long time lol.
I've got a lot more vouches, look at my main thread.
Second of all, you received your refund by PayPal yesterday if I'm not mistaken.
Third of all, I would provide you with proof of long-time customers, but I won't, because of the privacy of my customers.
