This buyer immediately told me she was not going to pay for the item RIGHT after "buying it now". I told her I was going to open an unpaid item case after 4 days and she threatened negative feedback. Not only did she threaten in but she IMMEDIATELY left negative feedback saying my customer service skills were terrible and I was a horrible person. I had to get eBay to back me by removing the negative feedback for a non-payor customer. The worst part was after I opened a case for the unpaid item eBay told me if I didn't request to cancel the transaction her feedback would HAVE to stay if she paid within the 4 waiting days after I opened an unpaid case. So she has no strikes on her account to warn other buyers! Please beware!!!
