How exactly are you trying to access your email? Saying "I can't access it" doesn't narrow it down to being a DH problem, or a problem on your end.
Also, you don't need to "demand" a refund... they offer one.
In reply to:
So, can someone recommend a reliable, economical hosting company out there that offers Subversion or CVS?
Let's see, you're asking at Dreamhost.com, so I'm going to go ahead and recommend Dreamhost.com. You can sign up at https://dreamhost.com/signup.
If you don't like that recommendation, you can go to any host's forum and they'll be happy to recommend themselves as well.
