Technician at the wrong address

HI there,

I had an appointment today from 3:00 p.m.-5:00 p.m. I recoeved notice that the technician was on their way so I propped open apartment front doors. No one arrived and I recieved a message that the appointment had been cancelled. I went outside and the I saw the technician leaving from a different building which I assumed they thought was mine. Is there anyway I can still have support today?

Thank you!
