Yes!
I complained when I had a meeting planned with ds and his HOY re some continuous bullying he was suffering from. He'd been pinned up against a wall by the neck and when he hit the person because they wouldn't let go he also got inclusion. (For violence).
Turned up for meeting and was asked to go in without ds at first.
I agreed but didn't know until I was in the room there was also HT, DHt/senco, head of learning support and assistant senco.
HT teacher basically told me to remove ds from school if I didn't trust them. They then asked leading questions very aggressively to ds about everything but the incident and bullying.
I emailed to confirm meeting and ask they corrected any of my minutes that were incorrect. They didn't.
2 weeks later that child pulled a knife on ds in the classroom when the teacher have left to get something from an office.
Ds tried to hang himself through anxiety of being killed at school. I took ds to GP following day so was absent from school and informed school.
School refused to authorise the absence (apparently as child was suspended for 2 days he had no reason to be anxious or absent.
Ds was too ill to return for a few more days due to sever anxiety. School reported me to EWO and I was threatened with prosecution for non attendance.
That was a stonker of a complaint 
I would say be very clear. Have email trail of everything discussed verbally to confirm you understood what was said and actions.
Be clear about what you want. Any policies they haven't followed.
Make sure it's worth an official complaint or whether a word in their ear would be a good place to start.
If it's actually worth a complaint and will help your own child, other current students and further students - who gives a shit what they say about you in the staff room?
