Biggest scam out

I ordered and paid for a fathers day gift on the 15th of May 2018. On the 4th of June a followed up about delivery. I was told next week it will be send out. And that is the same story every week. Until today I have not yet received what I paid for. When I reported them on Facebook, I was threatened with a defamation lawsuit. Now you don't get a hold of anyone there. They promised me a refund but nothing is happening. They are a scam and takes peoples money without anything to show for it.
