Please help, I don't know how to handle this

So I got my first client for my social media making business, and idk how to text. They said I could swing by next Thursday or Friday, but they didn't say where or when specifically, and the Google Maps address was just next to a road. There's a few buildings near there, but not where the pin was. And the last few messages I sent were read but no reply. What should I do? Do I follow up in a few days? And should I keep texting to 9-5 on weekdays
