It is not clear to me what you are asking. If a refund is made, then it should appear in your Transaction History. If their was a cancelation you should be notified of it. Not sure what you mean by "A refund was then given of 30.60". By who ?
It looked like I had been paid for a stay and then airbnb had taken it back and then just refundme me £30. However I have now realised that this is because of a refund given from last year. Airbnb have just taken it now from this last payment. Thanks for your response.
