Fraud Site...vegas Towers??

I have had an incident happen that has me scared
My debit card had been blocked so I rang the bank today
I have been using the card at vegas towers for a few months now
I have had the bank cancel my card because I was told the site that took my deposits is being investigated for fraud
I will no longer bother depositing with a card
All the bank can tell me right now is that someone has gotten hold of the card number and tried to use it
Either someone has latched onto their site or someone from that site is selling card numbers
They are under investigation
I will be e-mailing vegas towers about this matter, but wanted to inform the public to the potential threat
Thank goodness it is my debit card
I will never use my credit card online and now I am glad I didn't

Thanks for the info,

I tend to lose my card every 6 months or so on purpose so get a new one with different numbers on so that solves this problem to a degree, and gives me peace of mind somewhat.
