I ordered a Windows 7 key from them, attracted by the cheap price. Normally I'm conscientious about checking reviews of places I haven't used before, but I was in a hurry, and neglected to do so this time. A mistake! Bad reviews everywhere!
After being very quick to charge my card, they sent me a ridiculous "verification" form. Poorly written, with glaring mistakes, there was no way I was going to sent them a photo of my passport! I replied back, politely, but firm, and let them know that I would not expose myself to identity theft, and please cancel & refund. Of course, they pushed back and suggested that I really should fill in the form, but I stood my ground, and eventually they agreed to refund.
I was worried that I would never see my refund, and I would have to contact my credit card company, but it did come through a week later.
