"No answer"

I've been trying to call the Nerouolgy secretary since last Tuesday 26th September 17 till today I give an hour and half slot after I ring no one answers is just a voicemail if the I've been ringing every single day and it just goes to voicemail mail i understand if the sectary is away, they are allowed to, but at least say that your away this is so Frustrating to ring everyday and it goes to voicemail i had a EEG brain scan at Charing cross hospital on Monday 25th September and the Dr that did my scan said to me if my apptimoint is on the 7th October to ring the secretary and tell them to get the test faster.
