What to do?

So last week I placed an order online for some make-up (foundation, powder, and concealer) and then cancelled it the next day. The order was still pending so the cancellation went through-or so I thought. monday night I came home and saw a package in the kitchen. The concealer was shipped to me. I checked my order online and it said it has been cancelled. I checked my credit card and nothing had been charged. I called CS to see what happened and they were closed. Last night I called CS again. They guy on the phone told me the order was cancelled and they didn't show anything being shipped or billed. Basically, he told me they had no paper trail for the item being sent and that they have no knowledge of me having the item so what I do with it is up to me. If I send it back I get reinbursted for the shipping. If I don't do anything, they would never know. What do I do? This is $20 Bare Escentual concealer. Is Karma going to get me or are they sending me the first one free so I get addicted? Why is this keeping me up at night?

American Idol night so I had a good 2 hour block of knitting. I worked on the body of the French Market Bag as I watched Barry Manilow coach everyone. Has he had major work done or what? He has the shiny over stretched look to his skin. To think I used to have a cruch on him in the Copacabana days.
