Bad service from the Drs office

I made an appointment last week for the first time with this dr as I needed urgent assistance with the specialist. The lady that was there helped me so well and gave me the Wednesday 07.8.2020 to come for an appointment. On Tuesday I realized I had a work commitment that caused me to change to a later time to try and move the appointment. I called and the office phone number kept diverting to a cell number that no one picked up. His trading hours as a prosesional business says it open until 17:00 but 16:00 no one was answering the previous day.I called in the morning Just after 8. This lady who answered was just upright rude. And was screaming at the top of her lungs. I could even pick up form her tone that she was irritated. I asked to move the appointment to anytime later than 11. It seemed as if she either did not have the schedules in front of her to confirm or she was irritated by me. I ended up asking if She cannot transfer me to the lady that was assisting me as I could hear she was fighting. Her answer was she is not even in the office, when she gets to the office she will get the doctor himself to call me and make an appointment. I asked her to then pass my number to him as I need desperate assistance. She refused. She doesn’t know my condition, she doesn’t know if what I have is something that could kill me or not. Why is she working at the Drs office with such lack of empathy and compassion. Why are drs really keeping people like those at this time of so much enxiety and uncer*****ies. I tried him . It’s not fair
