Had a phone call yesterday at 4pm, Mr Smith (not real) phoned and started telling me about an issue with my daughter. Not doing homework, answering back in class and despite our discussing this before half term there has been no improvement and ...
My jaw dropped at this point as I was unaware of any problems at school with either of my DDs. I interrupted him and said which child he was referring to. He replied Sarah.
I do not have a Sarah.
There is a Sarah with our (relatively unusual) surname in DD1's year.
I stopped his ranting and told him that she was not my daughter. He said well this is the number the office has given me, and then carried on about Sarah. 
I talked over him "No, I am not Sarah's mum"
"Well, whose mum are you then?"
"Amy and Martha's"
"but this is 01223467554?"
"Yes, but I'm not Sarah's mum"
"Well the database must be wrong then"

Okay then, bye. and then he hung up.
Do you think this should be reported to the school to maybe put controls into place to ensure that the correct parent is being spoken too before confidential info is revealed?
