Garden State Readers GSR Called selling magazines saying I could cancel after 3 months. *NEVER RECEIVED FREE GIFT!* , Internet

Over 6 months ago, I received a call from a representative with Garden State Readers (GSR).  She seemed like she was new there.  They were offering a deal for 5 magazines per month for free, but would have to pay for the shipping and handling fees.  If I signed up for it, I would receive a free set of Ginsu knifes.  My first and only question to her was "could cancel at any time???".  She said I could cancel after 3 months.  On October 31st, I noticed another debit of $19.35 deducted from my checking account from Garden State Readers.  I then decided to go ahead and call them to cancel.  I received an automated system directing me to an answering machine.  I left a message stating that I wanted to cancel my subscription, and that I never received my free set of Ginsu knifes when I ordered the magazines with them either.  After a month later, I received a phone call at my work from Garden State Readers wanting to know where their payment was, because I was past due and if I had changed bank accounts.  I told her that I had left them a message over a month ago wanting to cancel, never received my knives, and never received a return call until now, because they want my money.  She stated to me that I am not allowed to cancel.  I told her that when I gave them my authorization to order the magazines, that I was told I could cancel after 3 months.  I knew I wasn't going to get anywhere, so I told her to send me to collections, and hung up on her.
