Let's just call it what it is. Alexandra is pimping out Sara and now pulling a bait and switch with Sara's ad. Regardless of whether female or not, pimping is pimping.
From what I'm reading here in this thread it seems as though she realized Sara is going to pose a threat to her bottom line, whatever she thinks that is, because Sara will obviously be a more genuine and overall better provider, and therefore decided to want to control her as much as possible to now even removing her from the picture again entirely.
