How to actually get in contact with Adobe Customer Service? Chat is always closed.

Hi. I have a permanent, legal licence for CS6, provided through my university before Adobe CC became the new model. Around Christmas 2017 my Adobe programs on my computer suddenly deactivated and told me I needed to buy a licence. Since I am graduated, my school directed me to contact Adobe to resolve this issue. However, I am finding it very difficult to navigate the Adobe "Customer Service". The only option for Account Issues seems to be the Chat window, and every time I check the website, it says Chat Closed.

I think my issue could be resolved if only my licence was disconnected from the student email account it was originally registered to. I no longer have access to that student email, so I cannot receive the Forgot Password emails for logging into that Adobe Account and trying to deactivate the licence myself so I can reactivate on a new account.

So I guess my question is how do you even get into contact with Adobe Customer service reps for account issues? I don't see options for it anywhere. I already paid over a thousand dollars for this CS6 software while in school and do not want to upgrade to CC on my personal laptop.

Thanks in advance.
