Ok, to start I made a deal with a guy from GT about two weeks ago. I sold him a firearm. I shipped the firearm on a Monday over night to his ffl after he gave me a deposit of $100. He shipped his firearm standard mail to my ffl. I got my firearm like four days after he got his and I got the lights that are part of the deal two weeks after the deal was made. I still have not to this day got the rest of my money $300. It's been two plus weeks and the deal was done on GT. I've sent emails with every slow replys... My question is what would you do? Also he's a police officer to boot.
