I, too, was scammed because it showed my sister's picture with the IQ quiz and stated that she said that I was stupid. Well, sibling rivalry got the best of me, and I was sucked right in! After I typed in my cell phone number and hit enter, I realized that I really was kind of stupid, and called my sister to confirm her message. You know she had no idea what I was talking about. Completely FALSE advertising.
I immediately tried to cancel to no avail--could not get a human on the line nor would the STOP code work. I then contacted my cell phone provider (Sprint) and was lucky enough to get Norman on the line who calmed me down and walked me through the process of blocking their numbers from my phone and crediting my account. They had already gotten me for $14.99. I did send an email to firstname.lastname@example.org to cancel. Their company name is PlayPhone Inc.
