Advert on web directory very low ranking what to do?

It is realatively easy to set up your own adwords account on google (If I can do it anyone can!). Once you decide on your advert you can limit your spend to daily & monthly spends. Generally the more you spend on cost per click the higher up the list you get - much easier to keep a handle on your spend than handing your money over to virtual cowboys
 
Thanks for that,I would just hate to give this company any more money for providing next to nothing but a persuasive sales spiel.
