I'm sorry that this is happening, both to your DD and to you.

As for their blaming you for the problem: it's despicable, but it's also understandable. If it's not your fault, it's theirs. And that might be a lawsuit in the making. They have to blame you. It's "CYA" behavior at its worst.

Don't let it fluster you. It's their mistake. I'm glad you're getting it sorted out.

Hang in there!
