My 14 year old son purchased a Green Dot Moneypak at Walmart a while back. He lost the receipt which you need to activate the card and now we can no longer use the card which was 4.95 to activate along with 50.00 dollars added to the card for a total of 54.95. I phoned Moneypak and they can't help us. I then called Walmart and they too said they can't help. That's a loss of 54.95 for us and a gain of 54.95 for Moneypak. What a scam they've set up. It's preying on those people who lose the receipt. :( read full review »
