How do I get support for my adobe rush product?

I have tried the chat function and have been left on hold for 45 min +  (two times - and finally gave up both times).  I tried the 1-800 number and was on hold for 32 min the first time before I gave up and 45 min the second time and gave up.  

I have posted to the Adobe Rush community board and received intermittent, not very helpful replies.  

I am very frustrated with this company as they aren't reachable.

I am using Adobe Rush software with a monthly subscription and it keeps freezing and crashing - I uploaded it in Sept and it was okay -- but now it doesn't do anything without crashing.  I have uninstalled it and reinstalled it and it still doesn't work.  I have tried to get in touch with someone - but it has been impossible.  Please advise of next steps - is there a direct number or email to contact someone?

My next option is to cancel my subscription -- terrible customer service.
