So support tells me that the halion demo can not be extended, but others have done this. What is the deal?

I guess nobody at this company cares at all that this bad, or that someone is actively trying to buy their product but just needs to confirm some things first?

I sent another email to the exact same support address with the exact same request for what was recently provided to another user and they just said no. No alternative or help of any kind. How does a company survive with this little regard for potential customers?
