What to do?

Charlotte
So yesterday i had texted my hair dresser to make an appointment to get my hair dyed. She didn't text me back till this morning saying that she had an opening for 9 tomorrow morning. I replied and said that 9 would work for me. She never answered back with okay, or see you then so im not sure if the appointment was scheduled. I was then wondering if i should still show up to the salon? What would you guys do?
