Wildfire Vapor #-cig Shipping and Charging without authorization Lexington Kentucky

Received an email telling me that I qualified to win a prize and only had to pay $4.95 for shipping.It was for for a kit of 3-cigarettes. I received the kit, which I did not care for. Then, I received another shipment of cartridges that I did not order and my credit card was charged $69.94. I tried to call the company, but could get not answer. I sent back this shipment with a letter saying that I had not received or signed any contract for this purpose and requested a refund. Again, no response. Then I received a second shipment and was charged another $69.94. I am still trying to communicate via telephone and have called my credit card company to stop charges. This is evidently another scam and it is very serious to me, as they are taking money that I have not authorized and will not make themselves available to communication person to person. It was offered as a gift, but it is not a gift.
