payday mobility The lady lied to me. Internet

I found this paydday loan company on the enternet, the end of April. They approved me for a loan of $250. The lady told me that I would recieve the paperwork in the mail. She said that I coud pay it back into 2 payments. I asked if they were going to take it out of my bank accout and she said no. She told me that I would be mailing it back to them.  

I started noticing that I had $37.50 taken out of my account on 5/3/13, 5/10/13, 5/17/13. I never got any paperwork from them in the mail,nor my email. I looked their number up on my bank account and called them. I thought that these amounts were going toward the money that I borrowed. The lady told me that these were all just interest toward the borrowed amount.

I got very upset. I told her that the lady, I first talked to, told me somthing totally different. She said that I would get charged this everyweek until I paid them back. I told her that I wanted them to take half of what I owe them in the next 2 weeks. I told her that I would never deal with their company ever again. They lied to me and the interest is too high. 

I've dealt with a loan company over the internet before. I didn't have a problem with them. They even sent me the paperwork. 

Thank you so much for your time.
