ketoultradiet.com the biggest fraud ever

I order a product in December 2018, to date I have not received any product nor a refund numerous mail from and to customer care with empty promises still no product, in the mean time the advert for this product keep on going viral so how is it possible that they can be the biggest con artist and still get away with it.

They also the every so useless DHL company who can't even take down a reference number over the phone and last updated the tracking information in May
