"unprofessional & careless telephone answering…"

I’m a oncologist patient, just had my treatment half an hour ago at Finchley memorial, the team there asked me to get a prescription from my GP as a matter of urgency due to my treatment I had done today , as the calcium tablets they gave me make me nausea .I called Oxgate garden surgery explain it all to the staff (female individual )answered the phone , she insisted that it’s the hospital that should give me the calcium tablets ,I’m unsure if what to do ??? This female in question has no kindness or understanding of the importantnce of cancer treatment !! Really upsetting and desapoited
