I just had a simliar experience. I put out a link to over 7,000 followers. A person took the trip. I booked a trip within the year, and the voucher was at the top right of my computer. When I booked, it didn't take. I called and am told, "There's nothing we can do about it." I've been a SH for AirBnb, but I also suffered serious spinal injuries so I do not personally travel often. I called immediately when I booked thinking it's no big deal, they'll fix it because it's the right thing to do, right? They refused. I asked for someone higher up. The statement was there was NO WAY they could override it because I booked already. I was offered a voucher for a next trip, but I said this isn't satisfactory for me. When you send an email telling someone they have a voucher for the next trip, and it doesn't take...that is on YOU, not me. You are falsely advertising vouchers if you claim that it can be applied to the next trip, and it does not apply. That can't be legal, and this needs to be rectified. Although this post was started awhile back, I'm sure this has happened to many people. I will update if my own situatin is rectified. As for now, I believe this is an issue that many should post about until the problem is resolved.
