Many people have tried contacting them through multiple support forms about this march payment issue and they're not managing to get any humans to answer them.
Not that it excuses Google's notoriously bad/nonexistent customer service, but I suspect you could quite easily get the attention of the relevant people on G+.
(Notice that the one Google employee who has replied in the thread is being derided for not doing enough quickly enough. It was 9 AM in California when he replied. This is why nobody speaks up until the issue is resolved.)
The point is not that it's 9am in California, the point is that it's the 13th March already, and the first human answer we get, just minutes ago, is a developer of the new 3-man team being assembled to take over that derelict product -that processes millions, by the way. Is this a joke? no, it's just the Google way, it seems.
Developers have to give Google 30% of revenue and this is the kind of support they get. Not customer relations, not support, a lone developer of a meager, newly assembled team who used his good sense.
Sorry, but that excuses nothing. Do VISA, MasterCard, American Express start business at 9AM? They're 24-hour operations. So should any op dealing with payments.
