I used to drive for uber as part of fleet, so i only can get my payment and tax forms through it, which refused to give me 1099-misc or money, how can i complain?

I used to work as an uber driver by car that belong to that fleet. Then i changed to other car that doesn't belong to the fleet while uber gave my money and my  to my ex-boss, i can`t get my money either my 1099-msc coz he refused to.

How can i complain to get my money and 1099?

And how can i file my taxes?
