Dude, you wrote back to a spam email and you're telling us that you're at your breaking point because they haven't responded to you within 2 working days. You need to adjust your expectations.
Not a spam email. And is it so difficult to provide bare minimum information past the equivalent of "Did you know we have open positions?"
You're wasting your time even thinking about this - it's like being mad at the wind for blowing in a certain direction.
