Yahoo changed my bid and my campaign setting without my permission!!
 

Hi,

I just noticed about click on my ads today but something pissed me off. My campaign setting has been changed about keywords bid from $0.10 to $10 for each keywords without my permission and they also changed my campaign setting by turned off content match and change overall bids for every keywords under my campaign to $10. It costs me $5.67 per click and not converted to me I just mailed them to ask about this and I never see greedy too much like this before. How they can do that without my acknowledge? They are b***shi* abd hope to get their clearly explanation soon.
