Doctors secretaries are the worst. Ive had some bad run ins with one in particular. Incredibly patronising and rude yet expects politeness back. It sounds like they are a mess tbh. The fact that they don’t have your info on the system is their fault.
They sound unorganized, unprofessional and snooty, but you sound like you weren’t very cool yourself either so I don’t know. Do you like them enough to stick with them or do you try and find a better practice? It sounds like you’ve been with them awhile.
