It’s ok, I know how you feel - I sold my TV, receiver, speakers and stands to a FRIEND at the time (Lauren Chameli or however you spell her last name) for a reasonable 400 bucks, took me 9 months to get 100 bucks from her, after I called her dad, and then she freaked out and told me she was going to pay me the rest the next day. Hey - that was 3 and a half years ago!
It’s 300 bucks, whatever, but seriously - it’s 300 bucks, it’s not a lot of money, just pay me back you dumb bitch.
