Guest discount applied without my request

[Andrew4111]

I’ve just noticed three future bookings have had a15% guest discount applied which I didn’t request. Also a discount for 4 midweek days, when I rarely get bookings, and had no guest requests for those days. 
This change was made at 5.30am (when I am always asleep

 I never give discounts but the Airbnb call centre refused to accept responsibility. 

ime considering leaving Airbnb as I now no longer trust the algorithm

Usualy the type of dicount is mentioned in the price breakdown

Did you check in section "promotions" for an active promotion ?

And check in section discounts if "top rated" guests (15% discount) maybe turned on.

Also check if there is an additional discount for a 4 nights stay.
