got a phonecall from gammonempire

[Popeye]

Hi,
I got a phonecall from backgammonsite gammonempire today.
He said we haven't seen you for a while, do you still play backgammon.
I said yes.
He said we would like to welcome you back with a deposit bonus.
I said ok, i was thinking like never hurts to play out a bonus.
he asked me credit card number, i said, i have a epassporte virtual visa, and it probably doesn't work on their site.
Now he said, well we can try, and he asked the expiration date, the number, and the ccv2.
now i waws not thinking and just gave it to him on the phone.
Am i in trouble now?
I emailed Gammonempire support to ask if this was normal bussiness?
I called up epassporte support, and they said it's all probably ok, and nothing crooked.
But i still feel some doubts.
What do you guys think?
