Customer Service Issue

How in the world does Articulate have such great product and such poor customer service?  The closest thing I can get to a real person is to file a ticket!  Five hours later, no one can find my activation code for SL3.

I upgraded from SL2 to SL3 when it first became available.  Today, as I open SL3, I get a message that my trial has ended and I need to supply an activation code! I purchased SL3 in 2016!  I tried repeatedly to enter the code I had on file and it did not work.  Three hours of email correspondence and a couple of screen shots and they tell me the code I am entering is incorrect. (no kidding).  Then they want me to provide the original email with the code.  (if I had that I would not need customer support)

Called the customer care number for sales because it is the only actual phone number that I can find on the web.  Got a cute message, waited three minutes, and the automaton told me they would call me back and hung up.  Seriously!!!  In the meantime, I have lost a day's worth of work and am no closer to being able to use SL3!
