I texted Luke 4 days before the date I wanted to schedule. He was very responsive and we set a rate and tentative time. Two days later I confirmed the date and time. With no reply from him a day later, I texted him again asking to please confirm so I could make other plans if he was unavailable. He replied back that yes, he would book it.
The day of the appointment he texted me 3 and a half hours before the scheduled time asking me to confirm. I was driving so it took me about 50 minutes to reply but said yes, still on, please text me when you're on your way.
An hour later he texted me that "something has come up" and he wants to delay our session by about 2 hours.
I politely declined.
