T's schedule changes and absences are so hard. I struggled with this last year when the holiday month schedule seemed to change every week.
I can see where your T's office staff feels like they are being considerate and thoughtful by reminding patients about the schedule. When it took an hour to get to my T by bus, I would have been glad for the reminder. But you don't want to be reminded, and I can understand that - it's hard enough all the disruptions and missing T.
I imagine the staff has a printout of the 'usual' schedule and they run through it top to bottom and make those calls. (Like when my dentist or doctor or vet calls to remind that I have an appt. the following day.) I wonder why they couldn't notate your information to show that you don't want to be called.
If you want to, could you meet with your T one more time, to talk about this again and to see if there is a way to resolve it permanently?
