Hi @Denise-and-Joe0. You may think you have reached Air BNB but you haven't. This is a host forum and I am a host like yourself. If the dates are blocked due to a booking, you cannot cancel because you want to change the rate. If you cancel the dates will remain blocked and you will incur other host penalties for cancelling. If the dates are blocked due to a system error or you can prove the rate is wrong because of a system error, you could get help from Air BNB to change that. Here is a guide for contacting Air BNB. Good luck!!
