Q:

Unresponsive Certification Support - any idea how to contact them?

I'm trying to start a Salesforce certification exam since last week but I did run into several technical problems with the Sentinel App and biometric identification. The basic issues I have resolved on my own, but I'm still stuck. The remaining issue is that at the biometric login my picture is not recognized.
The KRYTERION support did his very best and finally pointed me to Salesforce support, since KRYTERION can't reset biometric data or re-schedule an exam more than one day into the future.
At http://certification.salesforce.com/open-a-case I have already logged two cases last week and again two cases this week. As an unfortunate the support is totally unresponsive. I only have received the automatic responder after the new case - since that nothing. At least my email has proven correct.
So I tried to contact our partner support. Response there was very quick and I started to feel better - but then they simply closed down the case and pointed me back to http://certification.salesforce.com/open-a-case - which stays unresponsive.
As a matter of fact I already spent two times $200 for not being able to simply start the exam. Now in a few hours my current schedule will expire again. I can't reschedule it further into the future via the Webassessor myself - today 23:45 is the ultimate point. If cert-support stays unresponsive it seems that I have wasted $400 for nothing.
My questions are:

Is it typical that the response time of cert-support is > 2 days?
Does anyone have an idea on how to get motion into unresponsive certification cases? 
It seems that there is no phone number to call, right? Or is there any?
Any secret communication path or any idea form the Saleforce people around here?

Any help or ideas are welcome!

A:

What actually helped, was to post into the Certification Group of the Partner Community. I got a very quick and nice response from Kari Lucio and right now they have refunded all of my prior expenses. Only waiting on the bio-reset, which should be easy, I guess.
update: bio-reset is done, too.
Thanks Salesforce, well done!
