xpressary No product delivery after three months and I paid with a credit card up front. Internet

On March 10, 2017 I ordered and paid by credit card for the Amazing Rolling Knife which has not appeared as of yet.  Today is June 10.  I have exchanged e-mails with customer service and have been told repeatedly that the item had shipped.

The last correspondence from xpressary was May 25 and I was told if I hadn't received the item by the following Friday to let them know and a new one would be shipped.  That's the second time I was given that run around story.I was also told  I would be given 20 percent off my next order, as if I would ever order anything again, from xpressary, if it really does exist!
