Periodicals Countrywide Periodicals Outrageous & Popular Rip-Off by Sales People Hamiliton Montana

I received a call in April about magazines and I thought it was to purchase only five magazines for so many months, so I could be entered into a sweepstakes or something like that.  Well, anyways the next thing I know is that I am getting a letter sayiing that I am to pay for five years of magazines six kinds and 60 issues of each one and could change them at anytime.  What I didn't know it was going to cost me $49.81 a month and I couldn't do that, I called them and told them that was not what I agreed to so they said they would drop it to $16.60 per month to help me out.  Anyways I couldn't do this and I looked more into it and found out it was a scam being done on people according to the BBB.  And now they won't stop harrasing me daily or every three days about me sending money by check or making a withdraw from my checking.  I have had more than one lady call me and not very nice after awhile.  I have been threatened to have me turned over to collections and now they are using multiple phone numbers from all different states so you can't track them down or block them.  I am tired of this and want it to stop.  Can you help me?
