No idea what I can do about it. Can hardly make anyone refund you can you? Tried sending another text to the "we had an agreement here" effect but no response. Plus tbh given she knew what I'd paid and that she left surreptitiously and didn't contact further seems to me evident she's not planning on a refund. Seems silly though - why risk a bad review like this? Especially as the evening was perfectly pleasant
You should be less suggestive / implicit and should send a direct email with your calculated revision of fee and explicit sum due for refund. Then see how she responds to that.
I've no idea whether the reason she gave is genuine or not, but if she alters the agreement then she should revise the fee. Otherwise it's plain dishonesty and disrespect. You fulfilled your part of the transaction.
Is she a member on here? If so it would be positive to hear her proposal to compensate you.
Had you met her previously? A grand is a big punt on an unknown (and her only other review on here is a resounding positive from Mr F). That said, I've never seen the point of overnights and paying someone to sleep!
