Airbnb Experiences' faulty booking system took pay...

Airbnb Experiences' faulty booking system took payment from me 7 times despite receiving error messages that no payment had gone through, then their customer service team lied to me repeatedly when I pushed to have my money refunded, saying that they had "automatically" put a refund through, and refused to issue me receipts for the refund.

After being assigned a "Case Manager" in a different time zone who could only talk with me at inappropriate times, and who lied to me repeatedly about the situation, I ended up calling the Airbnb number repeatedly myself to push for a refund.

Now it turns out the refund has only been processed this morning (4 days later). I'm now being told that it will take up to 15 days to receive my $640 back. Disgustingly unprofessional and inept.
