@Ian-And-Anne-Marie0 thank you! Yes she was playing the system. I rang the contace centre and spoke to a sensible chap who took the time to read all the evidence and saw straight away the game the guest had been playing, but the case went back to the original case manager who just sat on the case for three days so I rang and demanded to speak with his supervisor. It was then allocated to another case manager. Guess it was persistence. If that hadn't happened I would have deactivated my account permenantly.
Yes it would have been a big blow financially but the emotional impact of the sense of injustice would have probably been the bigger blow, especailly as the guest had remarked, when I said to her I wasn't prepared to lie toairbnb about her having a personal issue so they altered her booking, that the world would be a better place if everyone behaved like that and also remarked about how kind I was. I won't go into all the ins and outs of the whole saga, but she really was being very manipulative. All to save herself some money. She changed her arrival date at the last minute , so she could attend a social event she'd forgotten about, which cost her £100 so she can't be that hard up.
I doubt very much she will repay the money now she has got it. Airbnb will give her 48hours they said. I would have thought it will affect her ability to use airbnb again though. Or perhaps people can just set up new accounts..not sure how easy that is?
