Wholesale site issue HELP!?

[Kealan]

I was gonna buy some items on this site that sells wholesale good from china. But just before I bought them the site then asked me to put in 3 digits of my 4 digit password on my credit account. I didn't put in the 3 digits and then I closed down the site and thought I hadn't bought them. By the way when it asked me for 3 digits of my 4 digit password this was a security check that had been powered by Visa on my account. Anyway tonight I got an email saying thanks for buying from our site and so on. But would the money have been taken out of my account seen as I did not enter my pin or not? Because I don't think my bank would allow it seen as I didn't put in the code, right?
