Diagnosis and biopsy

Hi there, am new here I was told in June, following mammogram I had breast cancer. I didn't get the biopsy that day as I was on my own and scared. It was booked for the following week, had a friend attend with me, Dr refused to do it, as having allergies incase I had a reaction to the anaesthetic. Rang consultants secretary, asked her to ask consultant what I do? They rang, booked me the following week, friend came with me again,this time consultant said no to biopsy till have allergy tests. Had to wait weeks, saw allergy consultant, said don't test for anaesthetic, should be ok. Breast consultant asked to see me for a chat, I did, he asked me to get it done then, I said if had been mentioned, id have brought my friend, thought I'd be rebooked. I'd had in June, or the weeks since 5 people including him tell twice, I have cancer, he then said he needs to make sure it's cancer! Everybody told me need biopsy to find out type and grade, now he said to find out if is? Also have letter, signed by him stating it's cancer too! I've been told to put in a complaint about him. But it's 12 weeks this week since diagnosis and still not had biopsy, he stated if I didn't have it that day, no more he can do and is signing me off from his clinic. Any advice? Thank you in advance.
