I bought a $100 Steam gift card and when i tried to use it just 15mins after i bought the card,it was said to be used when i tried to use it im confused what should i do?

Are you able to post the error message exactly as it appears? Edit: Type out exactly what the error message says here.

Sometimes it takes a while before you can use those types of cards also there should be a number you can call on the back.

Your customer service wont take the carfs either i have gone its okay its settled your store only sell out cards which aren't good,except i ask if the steam can be taking for cash because that was the purpose i bought it for,while if it still works for games because it didn't work for games

Go to customer service or call 800 #
