Western Express they lied to other companies about why i quit fontana California

i averaged 8.00hr working at western express, i gave them a month advance that i was quitting. i gave them two good months to get my miles up because i was only getting 1600 to 1800 miles a week at 16 cpm not counting the 14cpm per diem. now theyr telling other companies they fired me, thats a lie. they told me 37cpm when they hired me, thats a lie. the only time this company wants a phone call from a driver is when you tell them you are quitting! then they say what can i do for you to make it better. the minute you get off the phone with them theyve already forgotten about you. they seriously do not give a dam about theyr drivers. now theyr lying to companies telling them i was fired.
