Complaint / review text:
An Airbnb Host sent me a discounted 75 Euro/night "special offer" rate via Airbnb (regular rate 92 Euro). Upon clicking the "booking" link in the offer message, I saw that the Airbnb Payment system did not reflect the special offer just the regular rate.
When Airbnb was contacted by the host, Airbnb customer "service" insisted their payment system was correct even after being told the host's offer rate and the payment system rate were different. The Airbnb customer rep did say that their fees could go up to ~20% which I took a bit as a threat as it was completely out of context.
Did not book.
