@Jeremy411 It's unclear- have you already cancelled, or not yet and seeing a refund listed which doesn't include a refund of the service fee? I've never been a guest, so not sure if they show the service fee refund when you look at cancelling, or it just gets reimbursed anyway as long as you haven't made more than 3 cancellations in a year.
Or perhaps you still need to cancel within 48 hours to get the service fee refunded, but you can't get it refunded at all, even within 48 hours, if you've cancelled more than 3 times in a year. But in that case, their wording is misleading.
You may have to contact Airbnb to explain and sort this out for you. It certainly seems that you should be entitled to a service fee refund, reading that policy as written.
