Contract courier

I am a courier I have been running a route for almost 11 years until last friday when I got called to the company and I have been told that the hospital had asked us to remove you from all you routes and since they are a big account for us we will do what they want. When I asked why they told me that there has been a lot of talking and R l made the call from the hospital. I felt like my professionalism and integrity were under attack. Do I have any legal recourse against RL? Whatever he said I did cost me my routes(contracts) with this company after 11 years. Is suing him and the hospital help get to the bottom of it and potential income loss recovery.
