I also had this problem for 2 US Bank VGC cards ($500 each). I called the number on the back of the card (866-952-5653). Once I input the 16-digit card number, I was transferred to CSR. One card, which I am trying to load to my Gobank in Walmart Kate but failed several times during last 2 weeks, still has $500 balance but is restricted. The CSR asked me to fax a lot of materials to them. The other card, is not purchased correctly. CSR suggested me to bring receipt to the store where I purchase it.
