I submitted my card numbers for exchange on 1/9/15. Nothing since, e-mails are vague about system problems.
Made me register a credit card to "avoid fraud". Cardcash.com now shows my order as cancelled. and suddenly, there are $800 in charges at Hong Kong Disneyland, etc. I have shut down my credit card and reported the fraud.
The thing is, I went through a legitimate news article (sorry, can't remember which). It gave me the link to Walmart to enter the card numbers. I scrolled back over all the URL addresses, they look legit, but obviously,they are not or something in the background may be hi-jacking you to a fake site.
Sorry, I am not providing a copy of my credit card statement just to show you what happened. Use this service at your own risk!
