We booked a partial load with John Bowen that was to pick up the next day. A few minutes after booking the load, our other large partial was pushed back a few days by another broker. We let John Bowen know immediately that we would not be able to take his load because of the issue with the other load. He totally overreacted seeing as we had just booked the load and also the shipment was to pick up the next day so he had plenty of time to recover the shipment. He also said he would remove us as a carrier from their system so we could not work with them again. It is always fascinating to watch a broker when we as a carrier tell them we cannot do a load. Brokers cancel loads on us carriers all the time, and we are supposed to be fine with it. But, when we cancel on them (10 minutes after booking), it is the end of the world. John Bowen is unprofessional. Do not do business with this guy who obviously has no idea how this business works.
