Magazine SVC Magazine SVC they double charged me i have been changed for to seperate accounts Magazine Svc/PERIODICAL SVC Margate Florida

I am being charged $49.90 the first mouth  for magazine services  The only information I have on this company is the phone number (1-800-551-9287) which appears next to the charge on my debit card statement. I do recall getting a call from a magazine service rep in Aug-2012 from - but I was tricked into believing that i was going to pay one low rate of $19.95. but they call me and said they have to move it up to $29.90. but the whole time i though that was all i have to pay ,them a few months later they call and ask me to pay the account off in full which is 400 - almost 500 dollars i told them i don't have it so they ask me to set up a payment plan  of $82.00 dollars a mouth. i thought that would be the only amount i would have to pay for the next few mouths and i would be finish.  but i checked my bank statement and they are still changing $29.90 also. i called them and ask why am i being changed twice they told me they don't know who the other company is when clearly it has been them. i tried to cancel it and they to told me'' it can't be canceled but we will lower your rate''. but a few weeks later they still was changing me $29.90 and $19.95 from two different accounts and now $82.00 also . I never would subscribe to and not being able to afford another 2-3 year of paying on magazines. I was promised a "reduced rate" of $19.95 per month i have 2 magazine charges on my debit card totaling $132 per month, and this has been going on for the past  few months.  i don't make that much money and i really cant afford this. its has been going on for a few mouths now and i just want it to stop and get  my money back .
