So sorry you had this experience!
Definitely don’t call or engage in any more communication with them, there’s no purpose to it.
The only loose ends to tie up are the reviews. Keep yours measured and factual. I think you’ll be fine with this, you’ve written with a very measured tone here! Mention the overlap, that there was some confusion with communication(maybe give a couple of examples around the timings), but also be positive about what you did enjoy about the sit. I’d not specifically mention the accusations, but have it affect the communication and hospitality ratings you give.
There might be an issue of responding to their review of you - in that case, this recent thread had a really good outcome. First 'negative' review
