Same for me. I bought a windows licence, paid with my credit card and then they ask me to send them all sorts of personal information. Ridiculous!
They then ask to call me back. I entered my cell phone and house number without any success. They said my phone numbers were invalid!
I finally had to call my credit card to cancel the payment! What a scam. Lost way too much time on this.
