Ccs, First National Bank ripoff, first national got me for my ignorance of not knowing Las Vegas Nevada

I got a phone call saying I was approved for a 8,500 credit line at usa platinum. I listened to them explain their credit line.It sounded legit at the time. I should have known something was up because my credit was poor. They told me it would help my credit. So for the fact of being desperate, their marketing sounded legit to me. I just recieved the two cards in the mail. No usual logos on it like regular credit cards. So when I went on the internet to find them I could not, but I did find several reports on them for ripoff scams. Right now I am wondering if I should close my bank account or can someone investigate and stop them from taking out money out of my checking account and how do I not let this affect my credit any further than the damages I am trying to restore without causing a catastrophe on my credit? Please someone help me. In doing so I will try to help others from not making the same mistakes as I have made. Forgive me for the ignorance of not knowing. Now I will know to investigate first then act upon it.
