A bit of a stuff up I need help with.

Wouldn't the daughter have had some idea they weren't playing?

You told them they wouldn't be playing unless they heard from you, remind her of that if she says anything to you. If she wasn't sure after seeing it in the paper she could have contacted you. She got a ride with her sister so it isn't like she is miles out of pocket.

It was a misunderstanding, not your fault if you couldn't contact her since you had given prior instruction.

She shouldn't have driven without checking first. It is not your fault imho.

[Ginger]

not your fault. you've rung and left a message- not much else you can do. leave it at that.....and if she wants to go around backstabbing you, then she will be the one who looks silly.
