I purchased several thousands of dollars worth of gift cards on Amazon. Every time I try to book something with airbnb I get an error code 500, if you look online this is a issue that they have with a lot of accounts. It's not the same issue with the gift cards not getting applied to the account. I was able to apply them to my account and I now have over $1,900 worth of credit in my account that I can't use. I actually needed to stay in another city for a medical treatment for cancer, I made them aware of my situation and nothing. All they can tell me is that they are working on it and this has been the only response for over 6 weeks now. I have had to pay for a hotel instead and have been asking for a refund of my gift cards and they finally agreed to last week which as not happened, they have currently stopped responding to my emails. I have contacted Amazon and they can do nothing about it. It looks like I will have to take airbnb to court and hope that I get my money back. I have attached photos of what happens when I try to book. Please don't lose your money buying these gift cards.
