Steam $20 eGift Card [Digital]

You have four options. Report issue with order online at walmart.com Send email about it. Go to local Walmart store, bring your order page and stuff. Call Walmart. What happens when Walmart sell customers one of these cards is they register the two serials the cards have to the order. That way they know exactly which card went to which customer and so on. This also prevents them from activating cards that weren't legitimately purchased. The first serial is the activation serial, it's essentially the same as the activation barcode. The second serial is the card production serial. It's identity amongst all the cards. If you have issue with your order about activation, Walmart can definitely make it right. Pretty much, on Walmart's end. They just got to make sure that the serial they are activating is indeed a serial that have been purchased by someone already. In which case, you just got to show them your order number. (as the serials are tied to that order number). Have fun gaming !
