Airbnb support staff cheating hosts , is this possible??

[R0]

I am wondering how airbnb staff denis was able to change my room price
i setup my price for 1 person to X
and 2 person to X + Y
airbnb staff send me message asking me to approve X price for 2 persons yesterday how did she do this.
If I was not checking the rate I could have approved this, is airbnb staff allowed to do this. i.e to change the presetup price for the room ?  
can airbnb staff cheat for helping out their friends get a cheap booking
can I request a enquiry by airbnb, to check if this was a system error or it was deliberate attempt to reduce my price. I have seen this happening before.

i want to setup enquiry for the initial offer made by denis for following transaction

I doubt it very much the system is automated. And why would they bother for such a small sum? Difficult to say what happened without details.
