Sticker.com Charged credit card, no product shipped. No response to phone calls or emails. Internet

Do not purchase from sticker.com.  They have a great website and it looks valid, but it isn't.  The phone number provided goes right to an automated message where you are to leave a message.  They never call you back.  They don't reply to emails either.  I purchased stickers for about $12.  A day later my credit card was charged.  I waited three weeks before trying to contact this company about my order.  I never received it.  It is now 2 months later.  Still no response and no stickers.  My credit card company is fighting it now.
