Wicked Herbals Guru Harley Skyberg never recieved my order or a refund san diego ca internet

I found the company wickedherbals.guru online, viewed their products and eventually made a purchase which was to be delivered c.o.d. The day that the delivery reciept was in my box, i visited the p.o. to pay the c.o.d. I was handed a priority type envelope which was supposed to be my ordered items. Enclosed within the envelope was a letter stating a thankyou for payment and a promise that id soon recieve my order which was to be mailed overnite upon recieving my payment.... this last part never happened. I have tryed to contact the company via email a couple of times unsuccesfully. I have not recieved as much as a response much less a refund.
