Shared Hosting Security Issues

I'm so frustrated with the web host provider for my newest independent project. I accidentally discovered a serious security issue and have been trying to get them to fix it, but they haven't even been getting back to me. It shouldn't be MY responsibility to try to get them to fix THEIR problem!

Long story short, the moral is: don't trust shared hosting security! And NEVER store sensitive customer information (ssn's, credit card info, etc) on a shared database server.

And watch where you buy stuff online. Personally, I think paypal is the ONLY way to do it.

Sigh.
