<human>: My girlfriend signed up for a magazine subscription service a couple months ago.  She was taking a number of art and marketing classes in school and needed material for research and presentations.  Around the same time, she got a call from basically a telemarketing service selling magazine subscriptions.  She signed up, thinking it was a great coincidence and convenience.  She was assured on the phone that she could cancel anytime.  A little foolishly, she handed over her credit card information and agreed to receive the magazines. 

Now finished with that semester, she no longer has a need for those subscriptions.  She called the company to cancel and they will not let her.  They state that she is in a 5 year contract to receive magazines through their service and she cannot cancel.  She has never 'physically' signed a contract.

My question is:   What are her rights in this situation? Could she cancel payment through her card and stop it that way?

Can you summarize the given text in a few sentences?
<bot>: my girl's getting magazines through a telemarketing service that will not let her cancel. what are her rights and options? (so I guess the title with extra words)
