Razer Gold Pin

Hi, I have a razergold pin of 10 dollars. I just use my razergold pin to purchase a worth of 5 dollars in Gtarcade and it was success. Secondly, I want to use the remaining razergold pin to purchase a diamonds in the mobile games but it says that I have no razergold pin and must to top-up. I used the same serial number and pin that I used in Gtarcade to Mobile Games. I have still at least 4-5 dollars razergold pin. Can someone help me?
