IF you have a good reason to: send a second request within a short period of time after the original request and you will find a real person on the other end. Now they may very well resend the automated message but Google keeps track of such things and will look into it if the automated message is ignored, or at least they have in some cases.
I know this because someone in another forum ignored the first automated message and sent a second follow up that did get a reply even though there was no manual penalty.
My suggestion: don't abuse this, Google needs to scale their responses and giving boilerplate to a first request if there is no manual penalty makes sense. If everyone starts sending a 2nd and 3rd attempt Google would need to step up their measures and make it harder for all.
This could also have been just chance, I wouldn't be willing to continually harass them to find out and I don't suggest you make it habit either.
