Sorry, but if you don't take the time to even ask anyone how to best access Apple's Dev support, and instead persist with a channel that's clearly not working, that's your failing. I've had no problem whatsoever with their phone support.
Also, I don't think it's very clever to make cheaper support channels (email) so bad that the only option is the phone support (which is much more resource intensive and costly). Even when you can afford it...

Also, Googling "apple developer call" gives proper entry points as the first and second results.
I'm not saying whether or not it's good practice, but if it leads to the quality of these phone support calls, then I'm all for it.
