Have had this or similar issues happen multiple times, all for different reasons (i.e. different reasons offered). Don’t take it personally and just move on. If you want to stop using this org then it’s your call. You can’t do anything about what happened but you choose your reaction.
Once while driving to an appt. the PO texted me to say the guy ahead had extended his time. Yeah, shouldn’t be allowed but some POs will do it.
One time I was given the go ahead and was at the door when the PO told me the appt. was canceled. Maybe I should have worn my N95 mask that day LOL.
At least a couple of times the PO ghosted me when I arrived so I just left.
I assume the real reason behind the above is that maxmuccell was ahead of me and the girls wanted to keep him for the day as their boy toy.
I tried extending an appointment once with a girl and the PO just said no and with the
emoji.
