Samsung galaxy store purchase error

[Zelda3]

Hi, I'm hoping someone will be able to help me.

I tried to purchase a theme lastnight & I I an error saying my purchase was declined to protect me from possible fraud,this isn't the first time I've used this card for purchases on the app store but this is the first time I've gotten this message. I've contacted customer support but I've heard nothing back as yet,any suggestions?

@Zelda3: Which Theme did you encounter the error with? It may be the case that there is an issue with the specific developer of the theme, rather than your chosen payment method. With this in mind you may wish to try downloading another theme via Settings > Themes, to see if the issue persists.

I tried it with a theme from LP digitenz,then I tried it with a monotype font both gave me the same declined message. Samsung said it might be my bank,I called the bank they said it's the seller,I contacted the seller & they said it's Samsung-_- but the charge is pending in my recent transactions now.......for 5 days & I have no idea what to do
