Adobe CC Suite Working Within a Proxy

My level of patience with Adobe is near nill.

Your frontline support only ever offer to give you ports and addresses to whitelist when you mention that you're working within a proxy environment. Yet you're happy to bill us $270 a month for our corporate subscriptions! How is this considered a corporate service!? Where is your complaints department?!

We work within a proxy environment where we use a global blacklist. There is nothing to whitelist. We are able to communicate with all your ports. The issue we're experiencing here is that your connection to our Creative Cloud Suites are wanting to be streamed through our proxy. This is not possible.

Can Adobe offer any kind of support to fix the issue that isn't level 1 "whitelisting ports"!?
