Web Hosting

I was trying get a hosting plan from a very famous hosting provider. I am trying to sign-up, but my go was not successful. And I was asked to communicate with a live chat. Then livechat guy got all the details from me, including the credit card, and registered the hosting plan. I was not very sure whether I can share my card information over chat. However since the chat was protected by http://www.thawte.com/ I just proceeded. It got the impression that its a preplanned setup. I think hosting provider does not have a proper system. Will check the credit card statement tomorrow!.. have anyone come a cross similar issue?
