I paid a company called Midwest Ag Pros who led me to believe they were part of the real Ag Pros company. Then that same Midwest Ag Pros company promised me more for my tractor than my asking price when I paid $1200 for the listing on their website, and nothing ever happened. The "buyer" refused to pay the high interest rate, so the rep Patrick guaranteed me even more money to be placed on another site. I paid $2,500 more, and Patrick promised me $55,000 for my $40,000 tractor. Now no one will answer my calls. I am literally out $3,700 with no answers. This guy Patrick was also very rude and combative when we last spoke. What do I do? Is this a scam?
