I don't know what to do

I recently received my schedule and my Oral Communication class is not something i can work around, not an issue with the day just the time. I messaged the registrar to see if they have other time slots and they said no but to check in again on Friday to see if something becomes available. I'm scared nothing might be open so my only option would be to drop the class and I really don't want to do that. Are there any other options or things I could do?
