To make sure the GFCI outlet isn't the problem, plug it in somewhere else. When problem solving, you have to knock out the problems one by one. Try power, it could be that if the electronics have been replaced in the AQ.
Keep dealing with CS. If it's that bad and it doesn't work, maybe they'll just replace the whole unit.
Honestly, in over 10 years of the forum, I'd say this hasn't happened even 10 times.
It's unfortunately when it's you, but call them direct to resolve it, they don't regularly monitor the forum.
