He send me some Army ID copies and photos of him. He requested me to give at least 6500 so that he can post phone. After giving 6500...He called and said iPhone is despatched with Military Couier and share the phtos of courier and confirmed me to get within 24hrs...Next day I got a call from person called from Military Couier namely Vikas Patel and saying he is calling from some regiment in gurgaon and I m having your Phone and if you want it pay the full amount it's army policy...
