Preference in being told of diagnosis

Hi,
I hope someone might be able to give me advice if you have time. I went for an ultrasound in October and was told on the same day by my GP that they think the lump is suspicious and they think it could be cancer and that I needed an MRI urgently. There were delays in getting the MRI and when I did have the MRI, the GP told me that they think it could be sarcoma. They forgot to send my details and scans to the consultant so there was another delay. I was meant to go on holiday next week as there had been so many delays but the consultant said he can see me next week to let me know the diagnosis. I asked if I could be told over the phone and once I am back from holiday, that I would go for the appointment to talk about treatment plan. I thought this made sense but the receptionist said that he doesn't give diagnosis over the phone and I would need to wait until after the holiday to find out the diagnosis. I'm upset with this, I have been waiting since October to find out if it's cancer and all I'm asking for is to be told over the phone so that I don't have an extra wait of two more weeks. Am I being reasonable? I just don't know anymore, I'm so stressed and really would prefer to find out by phone before the face to face appointment after the holiday.
Thank you, Angela.
