The Sale Guru False Tracking Information and Non-responsive to emails and chats Internet

I ordered this from a Facebook add.  I told my husband I thought it was too good to be true since they were offereing it for 50% of other retailers.  I decided to give it a try.  I processed my order easily and received an order confirmation immediately.  I received a tracking email a few days later but the tracking number didn't come up.  Knowing that sometimes takes a day or so to show up, I didn't think anything of it.  When I checked back, the website gave me an update that seemed reasonable even if the tracking number didn't show up on the USPS website.  When tracking again, the update said that the delivery was unsuccessful and to contact my local USPS to schedule redelivery.  I contacted them and they do not have a package for me nor does the tracking number I was provided with show up in their system.  I have tried calling the 800 number for the seller and have been unable to get through.  I have tried their online chat tool and email and haven't received any response.  Like others, the funds have been taken from my bank account.
