I contacted the customer support because i could not use my 2 coupons at the same time when booking.
I thought the support could possibly combine the 2 coupons into a new one, or prolong the expiration date of the remaining one that cannot be used.
The only solution offered was that i could simply book a second time this year to use the other coupon.
The coupons arent worth much, so i really do not understand why the support is stonewalling on my request.
What makes support thinking it is better to not grant goodwill than loosing hundreds of dollars future revenue? Because if that REALLY is the way how AirBnb understands customer service, and the "service" fees are quite considerable, then i will certainly never book again.
