Firstly, Congratulations on your new addition, I hope you're recovering better now and I wish you a speedy recovery 
YANBU OP - I would definitely complain.
I thought it might be helpful to share my own experience, I had an emergency c-section back in April 2020, this is in the north east UK.
I stayed in the recovery suite (post op room) for over 4 hours until I was well enough to be transferred through to postnatal - I think I may have been on a 'high dependency postnatal ward' so this may have made a difference but I cannot be sure as I was out of it when I got there still.
I had one main midwife/HCA who helped me, she was a young woman and she was an absolute ANGEL. She came into my little cubicle to help me with anything & everything, I wasn't able to move, was still lying in my blood stained night shirt I wore during my labour with my catheter in. She changed DS nappy for me, checked to make sure I was ok. I had also lost my glasses and she looked through every single part of my large bag to try and find them for me. We had no luck and she even went back to the labour ward to look for them, luckily we found them in my mini painkiller/meds bag on my little table. I apologised to her for feeling as though I'd messed her around but she wasn't snotty AT ALL. She really looked after me, came back to help me with the first feed, she helped me BF and encouraged me all the way through, really made me feel empowered.
Another HCA came to take my catheter out later in the day, gave birth at 4am and she helped me get up & walk to the bathroom to get my catheter out around 4pm I believe. I bled all the way to the bathroom leaving a trail on the floor, I was so embarrassed (even tho I'd just had about 10 pairs of hands up my vag hours beforehand?! 😂) but she was lovely, once she took my catheter out she put my knickers on for me as I was so sore, then walked me back to my bed. I never had to ask for painkillers and felt if I needed help I wouldn't hesitate to ask. I was discharged the following day at 2pm. Total stay around 34 hours hours after birth.
Meanwhile there was a young woman in the next cubicle to me and she had a difficult vaginal delivery, also her first child. Another midwife/HCA came in after she pressed her buzzer. I heard her panicking saying she had started bleeding heavily on her bed and if she could have some help. The HCA was rather harsh with her and abruptly replied 'have you been breastfeeding without a pad on?! You can't do that! No wonder you've bled' it was so patronising as though it was common knowledge... for it being your first child, I myself did not know this. I felt awful for her, she apologised and sounded really hurt.
I think it can be mixed but I really don't agree we should suck it up and get on with it.
Please do complain OP - trusts will never change unless we talk about bad experiences!
