Wozo.com ripoff scam , Internet

I saw on facebook the ability to get a poster for .99 which I did. Read the terms saw nothing of membership. I was charged 29.99 a week later and I called them and they said they would cancel the membership and when I recieved the two posters that I was charged the 29.99 for I could send them back for a refund. I recieved the one for .99 on the 9th, I was charged 29.99 four days after the .99 so I assumed I would get the other two 4 days or so after the first one came it is the 22 so I call wozo and get someone who says I will get an email from someone which I did which gave me the tracking number for the first order of .99 did not address the 29.99 order or any other tracking numbers so I am charged and got nothing for this money except the runaround from people on the phone and on the internet.
