I just bought a $10 PSN gift card. Then I saw all these negative reviews here…
After payment, they send you an email to verify your cellphone number.
After verifying it's only a matter of minutes before you get your code on email.
I had a little chat with support just to be sure, as shown in the pic. The other image is a snapshot of the email I received with the 10$ PlayStation gift card.
Hope this helps. They shouldn't be asking for cellphone numbers though.
