I have discovered that my C1t1 Advantage World card will not work at S1mon. When I try to buy a VGC (no matter how big or small), the purchase is declined until I call them and then it is approved.
However, by C1T1 declining the purchase, the card's use is now kaput for 24 hours per SM rules.
If I come back in 24 hours, same thing happens.
However, no problema at OM/OD.

Basically shut this card down at the mall.
