Premodonna Waist Gang Society Took my money and did not send me my purchase!!!!! They refuse to respond to my messages. US Internet

I purchased a waist training corset from Premadonna waist gang society a month ago. They did not send me an order number or a tracking number. I sent them countless messages about my pruchase and they did not repond to a single one. They charged me for the product and they did not send me my purchase that costed me over 200 dollars! They didnt even have the courtesy to update me on what is happening with my purchase. I do not know what to do right now. I paid for something i did not recieve and they are not responding to me. I dont even have an order number or any other way I can track this purchase. All i have is my CC statement that shows the transaction. If anyone knows what I can do about these people or for a way to get my money back please let me know. This is horrible horrible customer service. Premodonna NEVER AGAIN! I am quite taken back by this since celeberties are so called "endorsing" this product.
