1-day selling refurbished products as "new"

Anyone else had this happen?

My story, ordered a Samsung tab s pro LTE off them a couple of weeks ago for $799, it turned up today, first thing i notice is the security stickers had been opened.  When i opened the box there was no plastic cover on the screen either.  Jump online and started a chat with them, the person said "it is part of their checks to see that the screen is ok before sending the product out".  He then asks for my order number.

As he is pulling up the order i check on the included keyboard and its marks over it, I can also see usage and fingerprints on the F and R keys.  Once the guy i am chatting to pulls up the order he says "yes this is a new one" so I told him about the marks, he asks for photos, i sent photos and he still tells me this is part of their checks before sending the devices out however he will arrange a ticket to return it we then end the chat.

So I try and power the device on and it's dead, won't even charge with the charger i have here.  So I am thinking well i better used the charger it comes with, go to get the charger and cable and the cable is a USB C to USB C cable yet the charger is a USB A plug, there are also 2 sim ejecting tools in the box and no paperwork (manual, warranty etc).

How can they get away with selling it "new" when it sure as hell isn't.  Now i have to find time to post this back to them and wait around for a refund.

Anyone else had this issue with them?  The person on chat seems to know what to say to make it sound like they do it a lot.  The "oh we check them before sending them" line etc.
