Wanna ask you guys a question.

I have an Alliance Bank credit card. How come I cannot buy things online on American merchant website?

I have a biggggggggggggggggggg problem with my credit card.

I owned an Alliance Bank credit card. Last night, I tried to buy some clothes online from Macys, an American merchant. I think I tried to use my credit card to purchase twice but somehow the website told me it did not went through. However just now, I called Alliance Bank and they told me I double ordered. I did not even realise my order went through, not to even mention double ordered. Macys did not even send me any confirmation to my email and there's nothing on the order history. My shopping cart is still there - meaning to say I have yet to make my purchase. If you make your purchase already, your shopping card will become empty.

Now I am really afraid I am paying my credit card for nothing. What should I do now? Any advice?

I have an US shipping address. I wrote Macys and email and hopefully everything its fine.

So is this kinda thing common?
