Unisource doesn't pay there bills

I recently ran a load for this brokerage front Nicholasville, Ky to Bluffton, In. I ran the load, arrived 15 min early, sent them an arrival. Wound up with 2.5 hrs detention. They refuse to pay. They actually said that the emails that they requested are not proof. Plus they kept calling wanting to know where I was. Very annoying.

I would not recommend anyone pull for these so called people.
