Feel let down, rant

Does anyone else feel really let down by the 'care' they've had? This is my second pregnancy and I can't believe how poor it's been this time round. I'm 20 weeks, yet to actually meet my midwife. I've had a different midwife at each appointment. I understand holidays and leave and the covering midwives have been lovely. I am classed as high risk this pregnancy and due to have extra scans. Rang regarding my extra scan I was told I was having at 23 weeks a few weeks ago and was told the books open on Monday. Monday comes and I've got an appointment for a random hospital, neither of my 2 local hospitals because they don't have any appointments available. I was told I would be admitted if anything was picked up. Which is great at a random hospital. I went for my whooping cough vaccine a few days ago, as advised by the covering midwife. I arrived at the appointment for the nurse to tell me I can't have it until after my 20 week scan. Midwife said this will be the GPs choice, but reception was aware of how far along I was when I booked in as they asked. Spoke to gp today and they said no reason I shouldn't have had it. I spoke to my midwife about the above and a number of other things yesterday and she went through my further scans and next appointment, didn't mention anything but kept saying about A/L effecting appointments, so I had a feeling she wasn't going to be at my next one. This morning I received a text from her and rearranged it because she isn't present that day. Why not be honest on the phone yesterday about that! I could go on. I know these are only minor things but i have had enough. I've never known anything like it. I tried to call the community midwife team to discuss my options because if this was just myself, i would have just cancelled everything by now and I want to know what my options are.
