My fiance is a wonderful human being, with a god awful egg donor. We've been completely no contact with her, ever since she showed up without warning, screaming and honking and refused to leave on Christmas. We called the cops. She's blocked on everything, but for reasons, my fiance's sister has remained unblocked.

A few weeks ago, she sent us a grocery delivery, without warning, including perishables. Fiance texted his sister that it was not welcome.

Last week, she put a Costco gift card in an envelope along with a note under our door.

Today, another grocery delivery. I'm so frustrated and tired. It feels like she's getting worse. Advice, sympathy, all appreciated.

Edit: Delivery company has been called and is useless. We can return things, without charge to us, but that's about it.

Edit 2: Delivery company specifically said there is no way to block addresses in their system. So we're stuck either flagging the delivery person down and telling them to take it back or calling them and filing a return.
