"Uniterested and intimidating consultant"

I had excellent care for my ops and scans etc and cannot praise the Hospital enough but when it came to seeing my outpatient consultant the experience was firstly strange as they didn’t appear to know anything about my condition or medication. Long story short I was shown no duty of care whatsoever and was spoken to like I was hated and was not allowed to speak or ask any questions. Was a totally waste of my and Hospital time. I became so intimidated I have asked for a re-referral to a different consultant. I would like to put in a formal complaint but am worried about the care I would then receive ( drs do talk to each other about patients) . Patient care line did not seem interested in my problem when I called and told me to go to my go which I did. Now waiting for a new consultant.
