This company hit my card with $700 of fraudulent charges and when I try contacting them there is no way to speak to an actual person. Through many emails, mind you a response from a different person every time, they claim they cant provide me with an invoice showing what was ordered and to whom it was supposedly shipped. Claim there system cant track orders by credit card payments, so I ask how exactly do they provide refunds?? Careful everyone they will steal your money!
