You have two posts, one mentioning 2 guests arriving instead of 1, something you addressed after the guests completed their stay. It should have been when they arrived. Your second post mentions guests leaving when there was no WIFI. These two different events concern the same guests?
If so, you are attempting to collect from guests who A-brought someone extra and B- because they left when there was no WIFI (though you warned them of the possibility of this happening). I believe the odds are against you.
Oh, btw this board is principally used by hosts (and guests users) to help each other, though every so often the moderators may refer your request 'upstairs'.
