This is infuriating and the same for all the big companies (at least Google, Microsoft, Apple); you have a serious issue and simply no way to talk to a representative. The best you can do is post something on Hacker News and hope it somehow gets picked up.
I worked at a company that paid Microsoft a lot to have a 1-day SLA for support. When I contacted them, I got a reply back weeks later saying "hey sorry I missed your email". About two weeks later (which was the time it took to email back and forth), it was clear that I had to insert another ticket and mark the subject as something else (that was not directly related, but apparently the team responsible for that subject was also working on the functionality I found a bug in. There was no way for me to know this since it was something internal to Microsoft). So, I had to go through the whole procedure again.
Once I did that, the reply was "oh yeah, we dropped that functionality but the documentation doesn't mention it. we recommend you use <technology X> for this". Where, of course, technology X did not support the feature I was trying to use.
