I am interested in signing up for a course keep calling no answer how can I go about doing that

I tried to call them,because I need to be in touch with a former teacher Mrs Bolton about some math classes .

My business there had nothing to do with the school. But like most public schools, it is probably closed. Maybe they're doing remote learning. I know there's custodial staff there, maybe you can go by and ask them. Also try 311.
