No response from Vox

I've been trying for a week long to get an answer from Vox regarding our current package and a possible upgrade. First I tried to call and when I was transferred they cut the call. Then I emailed and got no response other than someone asking for the account number, which I had originally attached to the email, then they closed the ticket literally a minute later before I responded. So I emailed again and no response yet. Vox is quick to cut you off when you don't pay but when they have to provide a service they are missing.
