Broker is threatening with freightguard report

Hi there guys, I got this question. Can broker report me to freightguar for me calling him a coward?
Let me explain, I booked a load on Tuesday morning from Fruitland MD shipper was FCFS until 6pm. I gave eta 3pm.
I got unloaded in Jessup, MD and I was on my way to shipper. Only about 30 miles from shipper when broker called me canceling the load saying it was his customer canceling it ( yeah right...)
I told him to pay me a TONU since I was already driving for more than an hour and crossed toll bridge where toll was $45. He answered he would.
2 days later no TONU, so I called him and he's saying now he won't pay anything since he canceled on the same day and I didn't get to a shipper yet.
So emotions got better of me and I called him a f... coward. I know I should have handled myself better but I knew he just lied to me ( I contacted the shipper load was ready to go he just sold it to a cheaper carrier) yet he refuses to pay what is required of him.
Let me know from your experience what can I expect.
Broker is Freight Tec. Individual name is Austin Robinson.

 

Absolutely, not a first time this happened to me but never was I threatened with a freightguard report.

 

We agreed on him paying a TONU. We signed the contract if he canceled the load due to his customer or whatever was the reason and not due to my fault yeah he's required to pay TONU. It wasn't like he canceled the load few minutes after we signed the rate con and a day prior to ship date. I was already dispatched and very close to a shipper.

 

I was thinking about it but decided it's not worth my stress levels since he agreed on $250 TONU
