@gastrogirl, you're right that this is not the normal Mayo experience. I recommend that you talk to someone at the Office of Patient Experience. A Patient Experience mediator can address concerns about your care experience at Mayo Clinic. You can fill out the online feedback form or contact them by email or phone. Here's the information:
Office of Patient Experience
https://www.mayoclinic.org/about-mayo-clinic/patient-experience
Phone: 844-544-0036 (toll free)
Email: opx@mayo.edu

I hope you get some resolution and team care.
