I was tricked into this through another link! Now, how do I STOP those charges? How I wish I'd seen this first...

Here is the excerpt from the facebook "scams to avoid" link:

While Facebook has spent the past year trying to cut down on the number of misleading advertisements on the site, the fact remains that a small percentage of users still get duped into purchasing services they don’t really want. The IQ Quiz Scam has become ubiquitous on the Facebook Platform, and those users who install applications can expect to see an advertisement for an IQ Quiz Scam at some point. In December we covered one application developer who was using spammy techniques to get new users to install their application and ultimately click on the IQ Quiz advertisements.

As soon as you click on one of the ads, you’ll be brought to a site where you’re asked up to 10 questions which are relatively easy to answer. You will then be prompted to enter your phone number to view the results. Don’t enter your phone number! If you do, you will be charged upwards of $10 a week directly to your phone bill. While most phone companies are willing to refund you for your first purchase, they won’t do it after the first occurrence. That’s because the phone companies generate billions of dollars each year off of these types of transactions.
