If you search this CC you will see many complaints about Airbnb CS. In my opinion, it has been declining in quality for years, but particularly in the past two years or so when Airbnb laid off a lot of its call centre staff and outsourced much of its CS.
RE the visibility of your listing, sure it could be a technical problem, but you should also read some of the posts on this forum about Categories and the Summer Release. You will see that this has greatly impacted the visibility of many listings, which might be an explanation for your problem, in which case CS really aren't going to help you with that.
