<human>: I am a college student. I signed up for a gym membership a few weeks ago, with the intention of having a place to work out for the summer. I stated this clearly to the staff member I signed up with. I was promised (and it is being promoted) that it is $10/month with no joining fee - so I assumed I would be paying $30 total for the summer membership. 

I have now been billed a $50 annual fee that is apparently in the contract, on top of my monthly charges. I feel lied to and cheated, since I was promised I would only have to pay $30. The amount may seem trivial but I'm poor and it's the principle of the matter. **How would you get your money back and/or get even if they refuse to refund me?** (they said they would NOT refund me on the phone - but I'm still going to go in and speak with a manager in person)

Give me the gist of the text in a nutshell
<bot>: I was charged an additional $50 for a summer gym membership after being lied to, and the injustice is driving me crazy
