We are a long time seller on ebay. we sold an iPhone to Ahmad Riyati that was like new. His ebay user name is "ahmad83it." He made several harassing attempts to get us to give him a partial refund because he felt "he paid too much for the phone." We offered a full refund & he declined. He made it clear that he would leave positive feedback if we gave him $90.00. We declined & he left us negative feedback. What is strange is Ahmad is buying lots of phones & not selling them. We contacted the FBI in Fayetteville & alerted them of possible sinister motives. Best advice we can give, don't do business with him.
