MYSCORE.COM Credit Karma TOTALLY BAD EXPERIENCE!!DON'T USE THIS COMPANY EVER!! Internet

I tried myscore free trial and I didn't really like it, so I.called the company's number directly to cancel since they tried to charge my account before the 7-day trial was up. I spoke to a lady about my membership and informed her that I was calling to cancel my membership before I get billed. After, realizing that I wasn't changing my mind, she assured me that it was cancelled. That was on the 1-30-2015, and here it is now 2-04-2015 and I found out that I was charged $38.90, for the very same membership account that's supposed to be closed. I want, need, and demand and openly request a full refund of my money as soon as possible! Don't think I'm going to let this go, cause I won't and if I have to publish and sue this company for fraudulent practices and theft by taking, then I will.
