Definitely "withdrawing cash from ATMs worldwide " - this is mistake, and we already deleted this from our website. We are ready to upload 30 usd to couple of you to make tests and tell other people about your experience.
Perhaps you should thoroughly review the entire page and eliminate all errors and deficiencies. If it is true that your virtual card can only be used for online payments, then it is definitely a worse choice than other no-KYC virtual cards that can be added to Google Wallet or ApplePay and thus used for physical payments.
We still do not know whether the card can be credited with $30 or $300, and how long the card is valid. Also, the links that should lead to
"Help & Support, Privacy policy & Terms & Conditions" do not lead anywhere.
I wouldn't vouch for such a service if someone paid me ten times more than what you offer, especially when your service is full of holes and unfinished things.
