Freedom pop Canceled order, equipment still shipping and no refund. Nationwide

I ordered a unit to get internet service but soon realized I didn't want the product.  I called and cancelled order.  I was assured it was cancelled, I even got an email saying my account was cancelled.  Then I got an email saying product was sent.  What?  No refund either.  I emailed numerous times but no response yet.  Called and they said to reject the package and I will get refund.  What?  If order was cancelled I should not be responsible for this.  There is no way I know of to reject a package because I won't see delivery person.  My account is not cancelled either, like it was reactivated just to show the product is on the way.  Not good service at all.
