Frustrated by Delayed Responses: Seeking Clarity on Timelines

I’m about to log out, and I still haven't received any response. How long does it actually take for someone to reply, 24 to 48 hours? Whenever I follow up via email or Slack, I’m told to keep everything in one message, but even when I do that, I'm still ignored. It's really frustrating to be left hanging like this with no clear timeline or acknowledgment.
