I came here to confirm that QCK card, which is same as PlatinumATMCard.com - or Platinum ATM Card prepaid MasterCard issuer, are the same group of people and they are scamming. After loading my card they do not respond to anything and of course the website is fake and my card doesn't work on any machine nor online with credit card payment methods.
They do a nice trick with sending you a plastic card and it all looks fairly real, but now that I cannot access my funds or get a response from this "company", I was able to even see all the clues that should have warned me before about this. I'm so mad to fall into this!
If you try to call them you just get the Barclays hotline which have no idea about QCK or PlatinumATMCard and they can't do anything with your details.

The creditcard issued to me is:

It's all useless so I don't mind posting it online.
