Account settings for support site

How come there can be only one admin for my company?

How did I update the credit card on file for automatic renewal?

How can anyone find anything on the support site?

I have not received an email response from the email support.  Does someone actually review those emails.

I had to resort to Twitter, but only received a reply saying to DM them.  I did to the ptc handle, and received not reply.  Another user asked me to DM them, but they have DMs blocked.

I don't feel like PTC really is trying to support their customers.
