My cards are still active, checked their twitter and there isn't any other than normal complaints activity so probably it's your account only.
Assuming you have checked your mail already and there is also nothing there, contact them....and get some trail mix as you're going to have to wait a bit.

Ps.
I see you're from Romania, why do you use USD card? I had a discussion with somebody using both USD and EUR cards, he dropped the USD one because he was charged a lot extra than the EUR one for the same purchased amount.
