Assure CBD oil (Assure Products) free trial not honored. Product never recieved Internet

 I was debating whether or not to try CBD products for sleep and for joint pain. I happened on this ad on Facebook for a company (Assure) offering free trial if their products. They used Angela Landsbury as a come on saying she had done research and had helped develop this product and that she used it etc I ordered the sleep and the therapeutic oil. I waited for delivery. Nothing arrived and after about 10 days I called to check. Nothing was settled and I was reassured that due to high demand my shipment might be delayed After a couple more days I called to cancel the whole thing so no further deductions would be made from my account. Representative told me I couldn't cancel til the trial period expires. When I called two days ago to cancel I was told that my account was charged and no refund was to be made. However the offer of substantial discounts on my next order was made. When I tried to explain that I never received the product and was consequently not able to try it I was told that the package had been delivered to my mailbox and that I must contact USPS to find out where it was. I feel cheated out of almost $200 and that the company is making money from fraudulent promises and claims. I have tried to find a customer service e mail or working phone number and can not make contact. I have cancelation e mails for the two accounts but there is no contact information to follow up. I feel cheated and foolish, but a little wiser.
