Smart Target ---- itargetmall.com I ordered on 1/10/17 from their site. I was supposed to receive an e-mail confirmation. California

I placed an order on their site on 1/10/17.  I used a credit card.  I made a copy of the final receipt with charges, other info.  I was supposed to receive an e-mail confirmation.  I have not received an e-mail confirmation for my order at this point.  I called the phone number given and noone answered.  It was an automated response.  I e-mailed the contact and it came back as undeliverable.  I went back to the site and found another contact e-mail.  I wrote a response to that e-mail about my situation.  I did that this morning.  (1/11/17)  I have not received anything at this point.  I even told them that this was either a scam or my e-mail was incorrect.  I just received an e-mail that this e-mail was undeliverable.  (admin@axomall.com)

After reading from your website, I now realize that this particular site is a scam apparently.  What do I need to do in order to keep my credit card from being charged.  I had an Order #7570175, and it was for a Proctor Silex coffee maker.  After looking at the receipt more carefully, there isn't evidence there that I ordered this item.  It just shows the price I was charged.  It does not give the item and any info on that item. 

How do I proceed from here?
