How can you say if you are being harrased?

I feel that the school is harassing me as a parent and now feel they are bring unwanted stress to me and my child. They call many times, example, when my child is sick, if I call them and report it, they sometimes call me twice or three times the same day and this always happens, for updates. When they need to reach me they leave more then 2-3 messages even if they have already spoke to me. Falsifying reports - stating there was no communication and no contact information when child was sick. Last year, social services were called twice by the school. Once reporting a lack of food in my house - They (The school) were never even at my house. Once for reporting my child’s hair being unbrushed. The school called social services on me, for the now third time, because the child had an ear infection, they knew about this, they called me to have me pick her up the day it started, and every day I called them when she was out, I left voice mail when I couldn’t get a hold of them, and when I took her in to the doctors, I called both the school and the nurses office, I updated them on her condition, I told them she’d have a note and what the doctor gave her, I also told them that the doctor stated if she didn’t feel well, she needs to rest for another day. I gave them the doctors information to confirm this, and the cops were called on me as well as a social worker. If that wasn’t enough I believe my child is not safe at the school. Last year while riding the bus she began receiving inappropriate note from a boy much older than her. The boy was giving notes out to the girls on the bus, and my daughter even got yelled a few times for taking the notes when she didn’t even know who they are. Another thing of note: She was fine for all of thanksgiving vacation and then suddenly she went to school and was in large amount of pain from her ear, leaving me to wonder what happen at school and wonder if they make sure she is dressing correctly for outside weather.
