Indie Gala card payment problem

Hey gyus

I ran into a problem today when buying new Monday Bundle. I made the payment, the money was taken from my card but I received no bundle and a following message in my e-mail box:

"Indie Gala Stripe problem!

Our security systems revealed a suspicious activity for your transactions, so your transaction has been scheduled for reviewing.
If you think this is an error please contact support@indiegala.com"

Of course I sent them an e-mail right away as I'm an honest customer and this has never happened before. But maybe some of you got this issue and you may know why this happened? It irks me when such stuff happens and I don't know why. Does anyone know? Maybe it happened to someone before?
