@Michael1735 Re: "when i go to cancel she is only giving me back 50% of my fee."
Do you mean when you click the cancel button it says 50% will be refunded?
If so that is an automatic message generated by Airbnb based on the hosts cancellation policy that was in play when you booked.
Note: On May 1st Airbnb mandated a "48hour free cancellation" for 'Strict policy - the 7 day / 50% policy (I do not think it is retroactive, so it would depend on when you made the booking among other factors).
Also please note that Airbnb holds your payment, the host does not get paid until a few days after you have arrived.
Re: "cancel up to 7 days before check in and get a 50% refund"
7 days is the wording for the 'Strict' policy, the 'moderate is 5 days and 'flexible' is 1 day
You need to speak to Airbnb to sort it out, their number should be on your reservation.
