Roomster Corp roomster.com Stole money from a poor college student who car barely afford housing!!! Internet

Roomster.com is a sight where a person can find roommates, housing etc... I was looking for a place to live and I thought to better my chances of finding a roommate ill sign up for roomster. After signing up and messaging potential roommates I found out you had to pay to view emails and answers to questions. So I thought ok I am looking to move in a week so I will try the three day trial only 5.95. A couple days later I found a roommate through craigslist but I was still getting emails from roomster after my three day trial was up. I thought this was strange. Then a week later I checked my credit card statement and saw I had been billed for a 30 day subscription to roomster which I did not agree to pay for. They stole 30 dollars out of my credit card and have no intention of returning it.
