@Lynette46 5 of 19 reviews are cancellation reviews. None of these automated reviews have a response from you. You have five listings and I wonder if you are aware that if you AGREE with a guest cancellation then it becomes a host cancellation and subject to all the automated penalties.
Not sure why you let this issue go on for so long, but it might be useful for you to have a long conversation with an Air BNB representative in which you refute that the cancellations are initiated by you. Gather all the reservation numbers and the Air BNB messages that support that all these cancellations are not host initiated. Perhaps the automated response can be reversed.
