"Terrible admin"

Booked MRI but had to call to say I have a vertigo episode at present can I rebook. Was reluctant to rebook. She quizzed me about my vertigo and said they don't do MRIs on those who've had a gastric bypass and not with vertigo. That's why I've been referred. She's not medically trained do why is she making these decisions. She says I need further evaluation form the GP. That's why they referred me to you. For an MRI. Very poor service.
