Rent A Center RAC PICKED UP WHERE I LEFT OFF ON A LAPTOP, HAD PORN AND PERSONAL FILES ON IT Frederick Maryland

So I went to go "Pick up where I left off" on an Alienware laptop. Here are my issues...

The one I had before:
Brand new in box

i7 processor

765M NVIDIA graphics card

Windows 8

Completely new with factory settings

Worked perfectly.

The one I just received:

Pre used came in dirty laptop case

Charger did not charge laptop

i5 processor

750M NVIDIA graphics card

Wasn't factory restored, still had all the of info, programs, settings, files, and everything the person had on it before me.

Included a wide array of Proxys, Spyware, Spam programs, saved porn tabs, logged in emails and notifications.

GRAPHICS CARD WAS BROKEN.

Intel HD graphics would only work.

Windows 7

and much more.

As you can see, if I am going to pick back up on the same contract to where I left off, I expect to have the same equipment I had before. I can understand I won't have the same laptop, but that doesn't excuse giving someone a laptop that is pre used, broken, not restored to factory settings, and had the last person who used it private info on it. 

I called the store, they said to bring it in and they can fix it, but the thing is I am a computer savvy guy, you can't fix this in store. I would like a brand new one. Should I call customer service?
