I did not place an order for the above plus I have no idea what it is. 2nd its not even billed to me nor my address. I never ordered anything from these people!!! I dont even know how they even got my email. Plus the email wasn't addressed to me like it should of been. My name is no where on the email except as stated above. Should I call them or just ignore it because the billing & shipping info is not me. Thankfully they dont have my credit card info. What should I do about this??!!
