They should fire their own media buyer rather than blame Facebook. When buying any type of advertising you first have to buy a small campaign and measure the ROI (ie. new customers gained, not likes and followers and other social metrics bullshit, but customers) from that campaign before investing more in that same channel. They threw big money at a bad channel without testing it, that's their fault. If their goal was just to buy likes and followers then that's just twice as idiotic: the goal should always be to gain customers. That's the only ROI metric you should be looking at. So if you buy small test campaign on Facebook and you didn't gain any customers then don't spend any more money on Facebook. It's that simple.
